[PATCH BlueZ v1 07/12] client: add BAP endpoint registration scripts

[Luiz Augusto von Dentz <luiz.dentz@gmail.com>]

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

Add scripts registering a local PAC Source and a local PAC Sink
endpoint with LC3, to set up the two sides of a BAP unicast stream:

  bluetoothctl --init-script client/scripts/bap-source-lc3.bt

The locations and contexts match the ones bluetoothctl uses when
registering the endpoints itself, so that the metadata of a stream is
not rejected.
