[llvm] [SPIRV] Fix build after change in transitive includes (PR #106140)

[Justin Bogner via llvm-commits]

https://github.com/bogner created https://github.com/llvm/llvm-project/pull/106140

An unordered_set include was removed from a header in 04ebd1907c05 "[MC][NFC] Statically allocate storage for decoded pseudo probes and function records (#102789)", but SPIRVEmitIntrinsics was getting the definition from that transitive include. Fix the build by including the header explicitly.
