[Codegen][Tuner] Make default and user-provided specs work

This is a fixup to the tuning spec materialization that makes default
and user-provided specs work e2e. As an example, a working spec for
`linalg.matmul_transpose_b` is provided for gfx942.

* Allow for tuning spec entry points that consume their argument op.
  This is so that tuning specs can use `transform.foreach_match`.
* Require all tuning spec entry points to return `any_op`, so that we
  can chain includes. This works for both consumed and readonly args.
* Add a test to show that user-provided tuning specs take precedence
  over default ones.
* Work around a transform interpreter bug when multiple named sequenced
  across different modules share the same symbol name.
