Add the sudo pallet to coretime-westend, allowing use in
development/testing. Previously the coretime-rococo runtime was used in
situations like this, but since Rococo is now gone this can be used
instead.

No sudo key is added to Westend storage with this PR, since it's likely
that any updates will continue to be done over XCM. If this is something
that is wanted the key can be set via XCM.
