71ee84ac - [MLIR][Vector] Add unroll pattern for vector.constant_mask (#171518)

[MLIR][Vector] Add unroll pattern for vector.constant_mask (#171518) This PR adds unrolling for vector.constant_mask op based on the targetShape. Each unrolled vector computes its local mask size in each dimension (d) as: min(max(originalMaskSize[d] - offset[d], 0), unrolledMaskSize[d]).
