  [mlir][VectorOps] Fold extract on constant_mask (#183780)

Fold `vector.extract(vector.constant_mask)` to `vector.constant_mask` if
possible.

If the static position is outside of the masked area, the pattern will
fold to a constant all-false value instead.

Dynamic positions are only supported if the mask covers the entire
vector in that dimension.
