   [PGO][Offload] Profile profraw generation for GPU instrumentation #76587  (#93365)

This pull request is the second part of an ongoing effort to extends PGO
instrumentation to GPU device code and depends on #76587. This PR makes
the following changes:

- Introduces `__llvm_write_custom_profile` to PGO compiler-rt library.
This is an external function that can be used to write profiles with
custom data to target-specific files.
- Adds `__llvm_write_custom_profile` as weak symbol to libomptarget so
that it can write the collected data to a profraw file.
- Adds `PGODump` debug flag and only displays dump when the
aforementioned flag is set

  [AsmParser] Remove OperandMatchResultTy (#126650)

This has been deprecated since a479be0f39a3301e9ca634d37cf6454b6d3865c6
from September 2023, before LLVM 18. Surely now enough release cycles
have happened that it can be removed upstream.

  [MC] Replace MCContext::GenericSectionID with MCSection::NonUniqueID (#126202)

They have same semantics. NonUniqueID is more friendly for isUnique
implementation in MCSectionELF.

History: 97837b7 added support for unique IDs in sections and added
GenericSectionID. Later, 1dc16c7 added NonUniqueID.
