  Log Message:
  -----------
  [mlir][vector] Refactor Vector Unrolling and remove Tuple ops

Simplify vector unrolling pattern to be more aligned with rest of the
patterns and be closer to vector distribution.
The new implementation uses ExtractStridedSlice/InsertStridedSlice
instead of the Tuple ops. After this change the ops based on Tuple don't
have any more used so they can be removed.

This allows removing signifcant amount of dead code and will allow
extending the unrolling code going forward.
