[AMDGPU] Skip s_delay_alu for gfx1250 WMMA C-reuse chains

Consecutive gfx1250 WMMA/SWMMAC ops accumulating into the same matrix C
register reuse the accumulator in place, so the tied srcC read is
omitted and no delay is needed. AMDGPUInsertDelayAlu did not model this
and emitted an s_delay_alu that stalls the reuse chain.

Detect a C-reuse edge (tied srcC overlaps the previous XDL WMMA's dest,
with no intervening instruction) and skip the delay for that operand.
The change is state-neutral and safe, since GFX12+ interlocks the
matrix C hazard in hardware.
