connectAllSupportedProfile as all connection policy are set to UNKNOWN

CONNECTION_POLICY_UNKNOWN is the default value, and it only be cleared
as unpair. If the device is connected after the pairing, it would
connectAllSupportedProfile with setConnectionPolicy to
CONNECTION_POLICY_ALLOWED.

With LE audio only device combine with LE audio toggle, it would be
possible that all the supported profile become
CONNECTION_POLICY_FORBBIDEN. We should check if one of the profile is
ALLOWED or FORBBIDEN, we would only connect the enabled profile, and not
to overwrite the connection policy setting

Also contains minor refactor in this change about
connectAllSupprotedProfile, it would make the improvement on the
readability on log and code

Bug: 279366294
Test: disable le audio toggle, and then connect/disconnect device
