Implement indexed quads (GL_QUADS used with glDrawElements*) with a
compute pass conversion.
The compute shader converts from uint8/uint16/uint32 indices to uint32.
The format is passed through push constants to avoid having different
variants of the same shader.
- Used by Fast RMX
- Used by Xenoblade Chronicles 2 (it still has graphical due to
synchronization issues on Vulkan)
The original idea of returning pointers is that handles can be moved.
The problem is that the implementation didn't take that in mind and made
everything harder to work with. This commit drops pointer to handles and
returns the handles themselves. While it is still true that handles can
be invalidated, this way we get an old handle instead of a dangling
pointer.
This problem can be solved in the future with sparse buffers.
When the dynamic state is specified, pViewports and pScissors are
ignored, quoting the specification:
pViewports is a pointer to an array of VkViewport structures, defining
the viewport transforms. If the viewport state is dynamic, this member
is ignored.
That said, AMD's proprietary driver itself seem to read it regardless of
what the specification says.
preserve_contents was always true. We can't assume we don't have to
preserve clears because scissored and color masked clears exist.
This removes preserve_contents and assumes it as true at all times.
Implements a reduction operation. It's an atomic operation that doesn't
return a value.
This commit introduces another primitive because some shading languages
might have a primitive for reduction operations.

yuzu was already using the header for interpolation, but it was missing
the FragCoord.w multiplication described in the linked pull request.
This commit finally removes the FragCoord.w == 1.0f hack from the shader
decompiler.
While we are at it, this commit renames some enumerations to match
Nvidia's documentation (linked below) and fixes component declaration
order in the shader program header (z and w were swapped).
