OpenGL Cache: Ignore format reinterpretation hack

Browse source 
Several games such as Smash will cause some regions that are cached on
the gpu to be revalidated, but (seemingly) we can just ignore these
cases. If the data is already found on the gpu in dirty_regions, then we
validate those, and skip flushing that region from cpu.

Its unknown if this breaks any games, but it does speed up many games.
Additionally, it removes outlines in the pokemon games.
