Add missing dbus registrations and change documentation

Qt DBus registration for Bluez specific types was done by isBluez5().
However Qt 5.12 introduced bluetoothdVersion() which is a bit more
precise. It became necessary because runtime decisions based on exact
minor release versions of Bluez became necessary. Therefore some code
paths (depending on the user's use case) never called isBluez5() anymore.
Subsequently the dbus registrations were missed out on.

In the future isBLuez5() should be replaced by bluetoothdVersion().

QBluetoothSocket changed its underlying implementation when addressing
QTBUG-68550. It uses dbus sockets to establish rfcomm socket connections
to remote devices. The QBluetoothSocket::connectToService() overload that
expects a port number is no longer possible as Bluez DBus API does not
support connection establishment based on port numbers.
