Rename bt_bap_add_bis to bt_bap_check_bis as its scope has changed.
Use the BIS index received in the BASE to synchronize to the BIG.
Allow bt_bap_endpoint to be NULL.
Remove the Broadcast Sink code from set_configuration.
Update BASE parsing so that it creates streams and transports, without a
remote PAC and endpoint.
Update bap_find_setup_by_stream to find the setup in case the stream does
not contain an endpoint.
Update BAP Broadcast Sink state machine:
* BIS matched over the air -> create stream and transport and set the
stream state to BT_BAP_STREAM_STATE_CONFIG
* transport acquire sets stream state to BT_BAP_STREAM_STATE_ENABLING
and do BIG Create Sync
* BIG Sync Established received sets stream state to
BT_BAP_STREAM_STATE_STREAMING
