  -----------
  AMDGPU: Treat WMMA XDL ops as TRANS in S_DELAY_ALU insertion for gfx1250 (#149208)

WMMA XDL instructions are tracked as TRANs ops and the compiler should
consider them the same as TRANS in S_DELAY_ALU insertion. We use a searchable
table for the InsertDelayAlu pass to recognize these WMMA XDL instructions.
