rasterizer_cache: Remove runtime allocation caching (#6705)

* rasterizer_cache: Sentence surfaces

* gl_texture_runtime: Remove runtime side allocation cache

* rasterizer_cache: Adjust surface scale during reinterpreration

* Fixes pixelated outlines. Also allows to remove the d24s8 specific hack and is more generic in general

* rasterizer_cache: Remove Expand flag

* Begone!

* rasterizer_cache: Cache framebuffers with surface id

* rasterizer_cache: Sentence texture cubes

* renderer_opengl: Move texture mailbox to separate file

* Makes renderer_opengl cleaner overall and allows to report removal threshold from runtime instead of hardcoding. Vulkan requires this

* rasterizer_cache: Dont flush cache on layout change

* rasterizer_cache: Overhaul framebuffer management

* video_core: Remove duplicate

* rasterizer_cache: Sentence custom surfaces

* Vulkan cannot destroy images immediately so this ensures we use our garbage collector for that purpose
