  Log Message:
  -----------
  [SPIR-V] Add NonSemantic.AuxData emission (-spirv-preserve-auxdata) (#200002)

Add a NonSemantic.AuxData extended instruction set to the SPIR-V
backend, matching SPIRV-LLVM-Translator's --spirv-preserve-auxdata wire
format

- `-spirv-preserve-auxdata` emits LLVM attributes and metadata as
NonSemantic.AuxData records (requires SPV_KHR_non_semantic_info).
- `available_externally` functions keep their linkage via an AuxData
linkage record, emitted unconditionally.
