  -----------
  [mlir] Add a subtensor operation

This revision introduces a `subtensor` op, which is the counterpart of `subview` for a tensor operand. This also refactors the relevant pieces to allow reusing the `subview` implementation where appropriate.

This operation will be used to implement tiling for Linalg on tensors.
