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. Reviewed-by: Kenneth Graunke <[email protected]>
