  [mlir][bufferization] skip empty tensor elimination if they have different element type (#96998)

In the origin implementation, the empty tensor elimination will add a
`tensor.cast` and eliminate the tensor even if they have different
element type(f32, bf16). Here add a check for element type and skip the
elimination if they are different.
