This patch refactors the flow for the BAP Broadcast Sink.
After observing the BASE information, streams and transports will be
generated for each BIS that matches local PAC capabilities.
Because endpoints are not available any more, local PAC (which contain
local registered capabilities) has a new list of setups. Each setup is
generated based on the matching BIS observed.
Then, the setup is used to configure a stream which then generates a
MediaTransport.
The transport is in the TRANSPORT_STATE_IDLE state until someone
acquires it. The "Acquire" procedure results in creating the IO using
BIG Create Sync. The successful reply of it causes the transport to be
advanced in TRANSPORT_STATE_ACTIVE state.
bluetoothctl log with two transports being created and acquired:

Get the channel location from the stream's configured capabilities,
rather than from the local PACS database capabilities.

Set the stream to enabling for BAP Broadcast Sink, when the transport is
acquired.
Remove PAC logic for BAP Broadcast Sink stream creation.

When checking in local PACS for a BIS match return also the local PAC,
along with the status of the operation. This information is required
later when we create the stream.

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

The scope being changed doesn't mean we need to change its name,
except if you add an explanation on why check is a better term than
add here, or perhaps we want to add something like
bt_bap_stream_new_bis? Which shall return the bt_bap_stream already
configured from BIS.

If we were to follow the BAP spec to the letter then there is no
Enabling state, nor Enable procedure:
https://www.bluetooth.com/wp-content/uploads/Files/Specification/HTML/16212-BAP-html5/out/en/index-en.html#UUID-4a295bf2-6e50-be11-e827-c23e63569087_figure-idm4631863059107233170457600297
Broadcast streams can only be on Idle, Configured or Streaming states,
so I suggest we follow that as closely as possible.
