intel/fs/gen12: Work around dual-source blending hangs in combination with SIMD32.
This applies the same work-around I commited as b84fa0b31e67
"intel/fs/gen11: Work around dual-source blending hangs in combination
with SIMD32." to Gen12, which seems to suffer from the same hardware
bug found empirically. The failure mode seems to be identical.
