  [mlir][linalg] Enable fusion by expansion of reduction and named ops (#83473)

This adds support for expansion of named linalg ops and linalg ops with
reduction iterators. This improves the ability to make fusion decisions
WRT reduction operations. To recover the previous behavior, users of the
patterns can add a control function to restrict propagation of reshape
by expansion through linalg ops with reduction iterators.

For named linalg ops, this always converts the named op into a generic.
