  Log Message:
  -----------
  [HIP][Clang] Remove __AMDGCN_WAVEFRONT_SIZE macros (#157463)

Remove definitions, test uses, and documentation of the macros, which were
deprecated in November 2024 with PR #112849 / #115507.

Where required, the wavefront size should instead be queried via means provided
by the HIP runtime: the (non-constexpr) `warpSize` variable in device code, or
`hipGetDeviceProperties` in host code.

This change passed AMD-internal testing.

Implements SWDEV-522062.
