[mlir] Extract DestinationStyleOpInterface from LinalgStructuredInter…

…face.

There are several use cases where a destination style operation needs an interface
that contains a subset of the methods from LinalgStructuredInterface.
In this change, we move all such methods to a new interface, and add forwarding
methods to LinalgStructuredInterface to make the change the less invasive.
It may be possible to refactor the code later to get rid of (some or all) of the
forwarding methods.
This change also removes the cloneWithMapper interface methods, as it is not used anywhere.
