  Log Message:
  -----------
  [Clang][HIP] Reapply: Deprecate the AMDGCN_WAVEFRONT_SIZE macros (#115507)

So far, these macros can be used in contexts where no meaningful
wavefront size is available. We therefore deprecate these macros, to
replace them with a more resilient interface to access wavefront size
information where it is available.

Reapplies #112849 with a fix for the non-hermetic clang test that failed
on Mac after the revert in #115499.

For SWDEV-491529.
