Mahesh Ravishankar 97f919820b [mlir][TilingInterface] NFC Refactor of tile and fuse using TilingInterface. ...

This patch refactors the tiling and tile + fuse implementation using
`TilingInterface`. Primarily, it exposes the functionality as simple
utility functions instead of as a Pattern to allow calling it from a
pattern as it is done in the test today or from within the transform
dialect (in the future). This is a step towards deprecating similar
methods in Linalg dialect.

- The utility methods do not erase the root operations.
- The return value provides the values to use for replacements.
