Anonymize bt addresses in listAudioPorts

Fix a security bypass where listAudioPorts would provide BT MAC
addresses without the required permission.

If a client doesn't have BLUETOOTH_CONNECT, partially redact the
address. To avoid performance issues, this change:
 - Caches uids which hold the permission, invalidating them on the
   package manager cache invalidation sysprop
 - Ensures we only call the check outside of any locks in audioserver.

Soaking for backport on main, a better solution to follow.
