`spirv-remap` is not present in modern Vulkan SDK versions, it was replaced
with the `--canonicalize-ids` pass in `spirv-opt`.
Overall, canonicalization provides a significant compression improvement,
which is important considering that currently Xenia is distributed in a ZIP
archive and contains many very similar shaders.
With normal DEFLATE compression, canonicalization reduced the size of a ZIP
with `xenia.exe` from 3.54 MB to 3.45 MB in a test done before committing.
Also disable stripping of debug information from shaders, which apparently
was among what `spirv-remap` was doing with `--do-everything`, as binding
and uniform buffer member names heavily aid in debugging in RenderDoc.
Partially integrated from #2329.

Replace the `SubmissionTracker`s with new `GPUCompletionTimeline`s with a
more unified interface (using a base class), and without the internal logic
for queue ownership transfers since that idea was scrapped during the
development of the `Presenter`.
Also use this fence management logic for GPU emulation, though without
architectural reworks for now, just on the bottom level.
Still very messy, but can be cleaned up in further GPU command processor
and presenter reworks.
- Fake: No decoding
- Master: 1:1 from base version of Xenia
- Old: Master with improvements
- New: Completely new decoder with better stability (but not compability)

- Added codepath for "consume only" pass. This should resolve constant clicking in Source engine games.
- Added smaller performance improvements to decoder
Introduce "fast" readback resolve that reads from previous frame's
resolve buffers, quick swap between buffers each frame to avoid
copies so minimal performance impact and mostly correct bahavior.
Checks if previous frame had a buffer for the current resolve and
falls through to the slow path, which also allows to support
"screenshot" features in the games that do that without stalling
on normal resolve operations.
Re-enabled readback_memexport as separate feature, was previously
bundled with readback_resolve (probably not intentionally) and
ensures destination address is writeable to avoid memory access
related crashes and unnecessary work.
readback_resolve cvar changes from bool to string ternary with
"none", "fast" and "full" options, defaulting to the new "fast"
mode.
