workspace: prefer identifiers for output priority 

Since output names can change in various configurations, including
DisplayPort MST, prefer output identifiers for the output priority.
Users can still use `workspace <ws> output <names-or-ids>`, but any
output that is programmatically added to the list will be added under
the output identifier. If the output name exists in the list (from the
user workspace output configs), then that will be retained instead of
switching to the output identifier for that output.
