Transform interfaces are implemented, direction or via extensions, in libraries belonging to multiple other dialects. Those dialects don't need to depend on the non-interface part of the transform dialect, which includes the growing number of ops and transitive dependency footprint. Split out the interfaces into a separate library. This in turn requires flipping the dependency from the interface on the dialect that has crept in because both co-existed in one library. The interface shouldn't depend on the transform dialect either. As a consequence of splitting, the capability of the interpreter to automatically walk the payload IR to identify payload ops of a certain kind based on the type used for the entry point symbol argument is disabled. This is a good move by itself as it simplifies the interpreter logic. This functionality can be trivially replaced by a `transform.structured.match` operation.
