Add a property to enable the New AVRCP Profile (2/2)

You can now use the new AVRCP Profile by setting
persist.bluetooth.enablenewavrcp to true. Also add a binder interface
that will be used later in the future.

Bug: 68854188
Test: Check to see that the profile is used when property is true and is
      not used when property is false.
