  Log Message:
  -----------
  Move relocation specifiers to AMDGPUMCExpr::Specifier

Similar to previous migration done for all other ELF targets.
Switch from the confusing `VariantKind` to `Specifier`, which aligns
with Arm and IBM AIX's documentation.

Moving forward, relocation specifiers should be integrated into
AMDGPUMCExpr rather than MCSymbolRefExpr::SubclassData.

(Note: the term AMDGPUMCExpr::VariantKind is for expressions
without relocation specifiers:
https://github.com/llvm/llvm-project/pull/82022

It's up to AMDGPU maintainers to integrate these constants into Specifier.
