[llvm] [AMDGPU] Add PAL metadata names for 32 user SGPRs (PR #160126)

[Jay Foad via llvm-commits]

https://github.com/jayfoad created https://github.com/llvm/llvm-project/pull/160126

Since #154205 some subtargets can use up to 32 user SGPRs. Add names for
them all so they can be pretty printed in PAL metadata.
