* Make all structs readonly when applicable. It should reduce amount of needless defensive copies
* Make structs with trivial boilerplate equality code record structs
* Remove unnecessary readonly modifiers from TextureCreateInfo
* Make BitMap structs readonly too
`MB` and `GB` can either be interpreted as having base-10 units, or
base-2. `MiB` and `GiB` removes this discrepancy so that units of memory
are always interpreted using base-2 units.

* ControlCodeMemory address and size is always 64-bit
* Refactor CPU interface
* Use IExecutionContext interface on SVC handler, change how CPU interrupts invokes the handlers
* Make CpuEngine take a ITickSource rather than returning one
The previous implementation had the scenario where the CPU engine had to implement the tick source in mind, like for example, when we have a hypervisor and the game can read CNTPCT on the host directly. However given that we need to do conversion due to different frequencies anyway, it's not worth it. It's better to just let the user pass the tick source and redirect any reads to CNTPCT to the user tick source
* XML docs for the public interfaces
* PPTC invalidation due to NativeInterface function name changes
* Fix build of the CPU tests

* Handle potential access violations caused by partial unmap
* Implement host mapping using shared memory on Linux
* Add new GetPhysicalAddressChecked method, used to ensure the virtual address is mapped before address translation
Also align GetRef behaviour with software memory manager

Add basic support for the CFI value being passed in X18 since 11.0.0 by the official kernel.
We do not implement any random generator atm in the kernel and as such the KSystemControl.GenerateRandom function is stubbed
* kernel: Clear pages allocated with SetHeapSize
Before this commit, all new pages allocated by SetHeapSize were not
cleared by the kernel.
This would cause undefined data to be pass to the userland and possibly
resulting in weird memory corruption.

supported by the official kernel)
