  [mlir] Support rank-reduced extract_slice in ExtractSliceOfPadTensorSwapPattern (#138921)

This PR fixes `ExtractSliceOfPadTensorSwapPattern` to support
rank-reducing `tensor.extract_slice` ops, which were previously
unhandled and could cause crashes. To support this, an additional
`tensor.extract_slice` is inserted after `tensor.pad` to reduce the
result rank.
