[NFC] Simplify the tiling implementation using cloning. (#72178)

The current implementation of tiling using `scf.for` is convoluted to
make sure that the destination passing style of the untiled program is
preserved. The addition of support to tile using `scf.forall` (adapted
from the transform operation in Linalg) in
https://github.com/llvm/llvm-project/pull/67083

 used cloning of the
tiled operations to better streamline the implementation. This PR adapts
the other tiling methods to use a similar approach, making the
transformations (and handling destination passing style semantics) more
systematic.
