Description
A translator may generate a Listener with ListenerOptions (it's currently the internal IR).
A user listener opts should not automatically clear unrelated items in ListenerOptions.
This would also apply if another plugin used ListenerOptions.
API changes
ListenerOptions will now act as an overlay to system ones (if the system ones exist).
Code changes
Use proto merge when existing options are on the listener.
Testing steps
Added base options in the unit tests
Notes for reviewers
Open to manually implementing merge logic instead of proto merge
