cd201cd60f gl_shader_gen: Make use of fmt where applicable
Avoids string churn and makes it significantly easier to read the shader
template strings that are being used as the basis for formatting.

016d43df98 gl_shader_decompiler: Make use of fmt with the decompiler
Allows us to avoid even more string churn by allowing the AddLine
function to make use of fmt formatting so the string is formatted all at
once instead of concatenating multiple strings.

This is similar to how yuzu's decompiler works, which I've made function
the same way in the past.

Same behavior, no heap allocation.

strings returned from glGetString() are guaranteed to be static strings,
so this is safe to do. They're also guaranteed to be null-terminated.

gl_shader_disk: Make use of std::nullopt where applicable (#5293)
Some implementations can use the std::nullopt_t constructor of
std::optional to avoid needing to completely zero out the internal
buffer of the optional and instead only set the validity byte within it.

e.g. Consider the following function:

std::optional<std::vector<ShaderDiskCacheRaw>> fn() {
    return {};
}

With libc++ this will result in the following code generation on x86-64:

Fn():
  mov     rax, rdi
  vxorps  xmm0, xmm0, xmm0
  vmovups ymmword ptr [rdi], ymm0
  vzeroupper
  ret

With libstdc++, we also get the similar equivalent:

Fn():
  vpxor   xmm0, xmm0, xmm0
  mov     rax, rdi
  vmovdqu XMMWORD PTR [rdi], xmm0
  vmovdqu XMMWORD PTR [rdi+16], xmm0
  ret

If we change this function to return std::nullopt instead, then this
simplifies both the code gen from libc++ and libstdc++ down to:

Fn():
  mov     BYTE PTR [rdi+24], 0
  mov     rax, rdi
  ret

Given how little of a change is necessary to result in better code
generation, this is essentially a "free" very minor optimization.

12279b22cc gl_resource_manager: Make use of noexcept on move assignment and move constructors
Several standard constructors generally check if objects can be moved in
a non-throwing manner (usually via std::move_if_noexcept) to preserve
its exception guarantees. This means that if these were used with
certain containers any reallocations internally would cause resource
churn, as copies would be necessary instead of moves.

This way, if they're every used in that manner, the right behavior is
always performed.

Revert one change from #4844
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 (#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.

Texture Filtering v2 (#5166)
* 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
