video_core/renderer_opengl/gl_rasterizer_cache: Create Format Reinterpretation Framework (#5170)

* video_core/renderer_opengl/gl_rasterizer_cache: Create Format Reinterpretation Framework

Adds RGBA4 -> RGB5A1 reinterpretation commonly used by virtual console
If no matching surface can be found, ValidateSurface checks for a surface in the cache which is reinterpretable to the requested format.
If that fails, the cache is checked for any surface with a matching bit-width. If one is found, the region is flushed.
If not, the region is checked against dirty_regions to see if it was created entirely on the GPU.
If not, then the surface is flushed.

temporary change to avoid merge conflicts with video dumping

* re-add D24S8->RGBA8 res_scale hack

* adress review comments

* fix dirty region check

* check for surfaces with invalid pixel format, and break logic into separate functions
