This greatly reduces memory usage in games that aggressively reuse memory without removing dead textures from the pool, such as the Xenoblade games, UE3 games, and to a lesser extent, UE4/unity games.
This change stops memory usage from ballooning in xenoblade and some other games. It will also reduce texture view/dependency complexity in some games - for example in MK8D it will reduce the number of surface copies between lighting cubemaps generated for actors.
There shouldn't be any performance impact from doing this, though the deletion and creation of textures could be improved by improving the OpenGL texture storage cache, which is very simple and limited right now. This will be improved in future.
Another potential error has been fixed with the texture cache, which could prevent data loss when data is interchangably written to textures from both the GPU and CPU. It was possible that the dirty flag for a texture would be consumed without the data being synchronized on next use, due to the old overlap check. This check no longer consumes the dirty flag.
Please test a bunch of games to make sure they still work, and there are no performance regressions.

* Return mapped buffer pointer directly for flush, WriteableRegion for textures
A few changes here to generally improve performance, even for platforms not using the persistent buffer flush.
- Texture and buffer flush now return a ReadOnlySpan<byte>. It's guaranteed that this span is pinned in memory, but it will be overwritten on the next flush from that thread, so it is expected that the data is used before calling again.
- As a result, persistent mappings no longer copy to a new array - rather the persistent map is returned directly as a Span<>. A similar host array is used for the glGet flushes instead of allocating new arrays each time.
- Texture flushes now do their layout conversion into a WriteableRegion when the texture is not MultiRange, which allows the flush to happen directly into guest memory rather than into a temporary span, then copied over. This avoids another copy when doing layout conversion.
Overall, this saves 1 data copy for buffer flush, 1 copy for linear textures with matching source/target stride, and 2 copies for block textures or linear textures with mismatching strides.

* Compare aligned size for largest mip level when considering sampler resize
When selecting a texture that's a view for a sampler resize, we should take care that resizing it doesn't change the aligned size of any larger mip levels.
This PR covers two cases:
- When creating a view of the texture, we check that the aligned size of the view shifted up to level 0 still matches the aligned size of the container. If it does not, a copy dependency is created rather than resizing.
- When searching for a texture for sampler, textures that do _not_ match our aligned size when both are shifted up by its base level are not considered an exact match, as resizing the found texture will cause the mip 0 aligned size to change. It will create a copy dependency view instead.
Fixes graphical errors and crashes (on flush) in various Unity games that use render-to-texture.
* Move shared code to its own method.
* Improve handling for unmapped GPU resources
- Fixed a memory tracking bug that would set protection on empty PTEs
- When a texture's memory is (partially) unmapped, all pool references are forcibly removed and the texture must be rediscovered to draw with it. This will also force the texture discovery to always compare the texture's range for a match.
- RegionHandles now know if they are unmapped, and automatically unset their dirty flag when unmapped.
- Partial texture sync now loads only the region of texture that has been modified. Unmapped memory tracking handles cause dirty flags for a texture group handle to be ignored.
This greatly improves the emulator's stability for newer UE4 games.

This works rather well for most games, just need to fix 3d texture mips.
* Cleanup
* Address feedback
* Copy Dependencies and various other fixes
* Fix layer/level offset for copy from view<->view.

* Actually use non-contiguous ranges
* GetPhysicalRegions fixes
* Documentation and remove Address property from TextureInfo
* Finish implementing GetWritableRegion
* Fix typo
* Allow copy destination to have a different scale from source
Will result in more scaled copy destinations, but allows scaling in some games that copy textures to the output framebuffer.
* Support copying multiple levels/layers
Uses glFramebufferTextureLayer to copy multiple layers, copies levels individually (and scales the regions).
Remove CopyArrayScaled, since the backend copy handles it now.
* Size hints for copy regions and viewport dimensions to avoid data loss
* Reword comment.
* Use info for the rule rather than calculating aligned size.
* Reorder min/max, remove spaces
* WIP Range Tracking
- Texture invalidation seems to have large problems
- Buffer/Pool invalidation may have problems
- Mirror memory tracking puts an additional `add` in compiled code, we likely just want to make HLE access slower if this is the final solution.
- Native project is in the messiest possible location.
- [HACK] JIT memory access always uses native "fast" path
- [HACK] Trying some things with texture invalidation and views.
It works :)
Still a few hacks, messy things, slow things
More work in progress stuff (also move to memory project)
Quite a bit faster now.
- Unmapping GPU VA and CPU VA will now correctly update write tracking regions, and invalidate textures for the former.
- The Virtual range list is now non-overlapping like the physical one.
- Fixed some bugs where regions could leak.
- Introduced a weird bug that I still need to track down (consistent invalid buffer in MK8 ribbon road)
Move some stuff.
I think we'll eventually just put the dll and so for this in a nuget package.
Fix rebase.
[WIP] MultiRegionHandle variable size ranges
- Avoid reprotecting regions that change often (needs some tweaking)
- There's still a bug in buffers, somehow.
- Might want different api for minimum granularity
Fix rebase issue
Commit everything needed for software only tracking.
Remove native components.
Remove more native stuff.
Cleanup
Use a separate window for the background context, update opentk. (fixes linux)
Some experimental changes
Should get things working up to scratch - still need to try some things with flush/modification and res scale.
Include address with the region action.
Initial work to make range tracking work
Still a ton of bugs
Fix some issues with the new stuff.
* Fix texture flush instability
There's still some weird behaviour, but it's much improved without this. (textures with cpu modified data were flushing over it)
* Find the destination texture for Buffer->Texture full copy
Greatly improves performance for nvdec videos (with range tracking)
* Further improve texture tracking
* Disable Memory Tracking for view parents
This is a temporary approach to better match behaviour on master (where invalidations would be soaked up by views, rather than trigger twice)
The assumption is that when views are created to a texture, they will cover all of its data anyways. Of course, this can easily be improved in future.
* Introduce some tracking tests.
WIP
* Complete base tests.
* Add more tests for multiregion, fix existing test.
* Cleanup Part 1
* Remove unnecessary code from memory tracking
* Fix some inconsistencies with 3D texture rule.
* Add dispose tests.
* Use a background thread for the background context.
Rather than setting and unsetting a context as current, doing the work on a dedicated thread with signals seems to be a bit faster.
Also nerf the multithreading test a bit.
* Copy to texture with matching alignment
This extends the copy to work for some videos with unusual size, such as tutorial videos in SMO. It will only occur if the destination texture already exists at XCount size.
* Track reads for buffer copies. Synchronize new buffers before copying overlaps.
* Remove old texture flushing mechanisms.
Range tracking all the way, baby.
* Wake the background thread when disposing.
Avoids a deadlock when games are closed.
* Address Feedback 1
* Separate TextureCopy instance for background thread
Also `BackgroundContextWorker.InBackground` for a more sensible idenfifier for if we're in a background thread.
* Add missing XML docs.
* Address Feedback

* Some more feedback.
* Remove flush warning, Refocus window after making background context
* Initial implementation. Still pending better valid-overlap handling,
disposed pool, compressed format flush fix.
* Very messy backend resource cache.
* Oops
* Dispose -> Release
* Improve Release/Dispose.
* More rule refinement.
* View compatibility levels as an enum - you can always know if a view is only copy compatible.
* General cleanup.
Use locking on the resource cache, as it is likely to be used by other threads in future.
* Rename resource cache to resource pool.
* Address some of the smaller nits.
* Fix regression with MK8 lens flare
Texture flushes done the old way should trigger memory tracking.
* Use TextureCreateInfo as a key.
It now implements IEquatable and generates a hashcode based on width/height.
* Fix size change for compressed+non-compressed view combos.
Before, this could set either the compressed or non compressed texture with a size with the wrong size, depending on which texture had its size changed. This caused exceptions when flushing the texture.
Now it correctly takes the block size into account, assuming that these textures are only related because a pixel in the non-compressed texture represents a block in the compressed one.
* Implement JD's suggestion for HashCode Combine

PrintGuestStackTrace is now called in some critical error handlers
