  [mlir][linalg][NFC] Make reshape folding control more fine grain

This expose a lambda control instead of just a boolean to control unit
dimension folding.
This however gives more control to user to pick a good heuristic.
Folding reshapes helps fusion opportunities but may generate sub-optimal
generic ops.
