  [mlir][vector] Add a new TD op to wrap unit-dim collapsing patterns (#157507)

Adds a new TD Op,
  * `apply_patterns.vector.drop_inner_most_unit_dims_from_xfer_ops`,

which wraps the following Vector patterns:

  * `DropInnerMostUnitDimsTransferRead`
  * `DropInnerMostUnitDimsTransferWrite`

This complements other existing unit-dimension–related patterns.

To reduce duplication, the
`TestVectorTransferCollapseInnerMostContiguousDims`
pass has been removed. That pass was only used for testing, and its
functionality is now covered by the newly added TD Op.
