[mutter/benzea/ignore-monitor-connector: 1/2] monitor: Only take connector into account when required



commit 1dc6998bf9cb2f5343bf411505c595f9a5f0a79c
Author: Benjamin Berg <bberg redhat com>

    monitor: Only take connector into account when required
    
    Add a flag to meta_monitor_spec_equals to disable full connector
    matching when this is possible. In this mode, the connector is simply
    skipped from the compare, assuming that all monitors can be
    disambiguated using just EDID information.
    
    Update all calls to the relevant functions to pass whether a full match
    is needed or not.
