[mlir] Rename GeneralizeOuterUnitDims{Un}PackOpPatterns

Renames:
  * `GeneralizeOuterUnitDimsPackOpPattern`,
  * `GeneralizeOuterUnitDimsUnPackOpPattern`,

as
  * `DecomposeOuterUnitDimsPackOpPattern`,
  * `OuterUnitDimsUnPackOpPattern`,

respectively. The new name better describes the underlying
transformation.

**NOTE** Depends on #116373 (please only review the top commit)
