Bluetooth available hack

The first hack has been introduced to facilitate the creation of the
com.android.btservices apex without the need to upload 100+ cl close to
the release date.
We now want to delete com.android.bluetooth apex and replace all the
apex_available rules to target the new apex name
It will be way much easier to do this in separate CL and without forcing
us into a single topic.
