Rasterizer cache refactor v2 (#6479)

Browse Source 
* rasterizer_cache: Switch to template

* Eliminates all opengl references in the rasterizer cache headers
  thus completing the backend abstraction

* rasterizer_cache: Switch to page table

* Surface storage isn't particularly interval sensitive so we can use a page table to make it faster

* rasterizer_cache: Move sampler management out of rasterizer cache

* rasterizer_cache: Remove shared_ptr usage

* Switches to yuzu's slot vector for improved memory locality.

* rasterizer_cache: Rework reinterpretation lookup

* citra_qt: Per game texture filter

* rasterizer_cache: Log additional settings

* gl_texture_runtime: Resolve shadow map comment

* rasterizer_cache: Don't use float for viewport

* gl_texture_runtime: Fix custom allocation recycling

* rasterizer_cache: Minor cleanups

* Cleanup texture cubes when all the faces have been unregistered from the cache

* custom_tex_manager: Allow multiple hash mappings per texture

* code: Move slot vector to common

* rasterizer_cache: Prevent texture cube crashes

* rasterizer_cache: Improve mipmap validation

* CanSubRect now works properly when validating multi-level surfaces, for example Dark Moon validates a 4 level surface from a 3 level one and it works

* gl_blit_handler: Unbind sampler on reinterpretation
