  -----------
  [mlir][tosa] Fix mul/intdiv folds crashing on dynamic-shaped results (#212073)

`tosa.mul` and `tosa.intdiv` fold constant splat operands by building a
`DenseElementsAttr` of the result type, which asserts when that type has
a dynamic shape. When the operands are constants but the result type is
dynamic, folding aborted. Guard `mulBinaryFolder` and the `IntDivOp`
splat path on a static result shape, matching the other fold paths in
these ops.
