This fixes#5067 by reverting a speculative change made in a previous PR.
From this one can conclude that, for disabled textures, black (0,0,0,1) is the correct colour and clear (0,0,0,0) is not.
* 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
1. Ensure that register information available to gdbstub is most up-to-date.
2. There's no reason to check for current_thread == thread when emitting a trap.
Doing this results in random hangs whenever a step happens upon a thread switch.
* 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
* HLE Audio: Increase frame position by input buffer sample rate
Currently the frame position moves ahead by the number of samples
output, but thats a fixed number based on the 3ds native sample rate.
Instead, based on a homebrew by cyuubi and looking at the lle audio,
this sample position should be moved forward by the number of samples
from the input buffer that was read, based on the buffer's sample rate.
* vm_manager: Handle multiple areas in ChangeMemoryState
It is possible that a few areas have the same permisson and state, but with different backing pointers. Currently, this function assumes that only one continous area is found, but this is not always the case.
* service/ldr_ro: Handle multiple areas in VerifyBufferState
It is possible that the buffer passed from the game is made up of multiple areas with the same permisson and state but different backing pointers. Change the check to allow that.
