[Build] Replace spirv-remap with spirv-opt --canonicalize-ids

`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.
