[ur] Allow native handles to be unsupported

Some adapters do not map directly to Unified Runtime's set of API
objects and as such are unable to support getting the underlying native
handle or creating objects from native handles. This patch adds the
`UR_RESULT_ERROR_UNSUPPORTED_FEATURE` to all native handle entry-points
and updates the conformance tests to match.
