This PR

closes https://github.com/data-apis/array-api/issues/645 by adding a note concerning expected behavior when a specified device corresponds to the device on which an array instance resides. Namely, copy behavior is left implementation-dependent, with conforming array libraries being allowed to either return self or perform an explicit copy, as discussed in https://github.com/data-apis/array-api/issues/645#issuecomment-1634419029.
