libcamera: MediaEntity: expose the entity flags

Browse source 
The media entity flags can be useful for pipeline handlers to find the
default device in a media graph which is marked with the
MEDIA_ENT_FL_DEFAULT flag. This will be especially useful for the UVC
pipeline handler where the entity names differ per device.
