  Log Message:
  -----------
  [mlir] Add Tosa dialect const folder for tosa.const.

* Was missed in the initial submission and is required for a ConstantLike op.
* Also adds a materializeConstant hook to preserve it.
* Tightens up the argument constraint on tosa.const to match what is actually legal.
