* 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
* video_core/renderer_opengl: Move SurfaceParams into its own file
Some of its enums are needed outside of the rasterizer cache
and trying to use it caused circular dependencies.
* video_core/renderer_opengl: Overhaul the texture filter framework
This should make it less intrusive.
Now texture filtering doesn't have any mutable global state.
The texture filters now always upscale to the internal rendering resolution.
This simplifies the logic in UploadGLTexture and it simply takes the role of BlitTextures at the end of the function.
This also prevent extra blitting required when uploading to a framebuffer surface with a mismatched size.
* video_core/renderer_opengl: Use generated mipmaps for filtered textures
The filtered guest mipmaps often looked terrible.
* core/settings: Remove texture filter factor
* sdl/config: Remove texture filter factor
* qt/config: Remove texture filter factor
Previously this check is in GetSurface (if (addr == 0)). This worked fine because GetTextureSurface directly forwarded the address value to GetSurface. However, now with mipmap support, GetTextureSurface would call GetSurface several times with different address offset, resulting some >0 but still invalid address in case the input is 0. We should error out early on invalid address instead of sending it furthor down which would cause invalid memory access
video_core: shorten GetGLSLVersionString
video_core: make GLES version and extensions consistent
video_core: move some logic to LoadShader
video_core: deduplicate fragment shader precision specifier
Allows capturing screenshot at the current internal resolution (native for software renderer), but a setting is available to capture it in other resolutions. The screenshot is saved to a single PNG in the current layout.
They were missed, and Copy is very high in profile here. It doesn't block the GPU,
but it stalls the driver thread. So with our bad GL instructions, this might block quite a while.
* renderer_opengl: Namespace OpenGL code
Namespaces all OpenGL code under the OpenGL namespace.
Prevents polluting the global namespace and allows clear distinction
between other renderers' code in the future.
* Also namespace TextureCubeConfig
