Add the priority person highlight back to bubbles badge

In BubbleViewInfo task where the icons are fetched, we were creating
the ringed badge for priority people but we weren't using it. Instead
the original badge drawable was being used.

This switched the app badge to be a bitmap & uses the bitmap with the
priority person ring.

Also fixes an issue where the ring would draw through a badge that
also had the work profile indicator. This is done by drawing the
highlight first and then drawing the badge on top.

Test: manual 1) have a conversation notif that can bubble
             2) mark it as priority
             => Observe that the bubble is created and it has the
                ringed bitmap
             3) dismiss the bubble
             => check that the ring is present on the bubble in the
                bubble overflow
             4) repeat above steps with a bubble from workprofile,
                ensure it has the ring and the workprofile badge
