  -----------
  [mlir][linalg] Allow fusing reshapes with non-parallel operands (#130148)

Removes the condition that checks that operand is not indexed by
reduction iterators which allows for more fine-grained control via the
reshape fusion control function. For example, users could allow fusing
reshapes expand the M/N dims of a matmul but not the K dims (or preserve
the current behavior by not fusing at all).
