0b654c1502 Bluetooth: BAP: Fix conn checks for bcast assistant notifications
The notify handle in the BAP broadcast assistant did not handle
conn == NULL properly, and neither did delayed_bap_read_handler.

Add better NULL checks, which also fixes a coverity issue.

a6a14360a9 Bluetooth: BAP: Remove err from recv_state_removed callback
The callback is only ever called when we received a
notification from the BASS server that the receive state is
removed, which cannot contain an error code.
Thus it does not make sense for the callback to have an
error code.

bbb87ae0ae Bluetooth: Audio: Broadcast Assistant: Check add_source duplication
Added a check for checking duplication when adding a source in the
broadcast assistant, as per requirement in BAP 6.5.4. It is not
permitted to add a source such that a combination of broadcast_id,
adv_sid and address type would result in same triple of values.
Added a recv_state struct to cache these values when read, and moved
past_avail and srd_ids into this as well.

While refactoring the handling of callbacks the setting of past_avail
status got deleted (and it was in the wrong place). Adding it back at
the correct place.

The existing implementation allows for only one callback per procedure.
This creates problems when for example adding CAP functionality.

baaa149f10 Bluetooth: BAP: Fix bad bcast assistant bis sync shift
The shift is currently necessary due to a mismatch of the
specs and the API, but the shift should not be done when
the value is BT_BAP_BIS_SYNC_NO_PREF as that is a special value.

5ccd75b49b Bluetooth: Audio: define bt_bap_bass_subgroup struct.
The Broadcast Assistant API should be fully independent of the scan
delegator. Therefore the new struct bt_bap_bass_subgroup has been
defined to avoid a dependency.

Fixes: #68338

ec41dd9ba6 Bluetooth: Audio: Use BT_GATT_SUBSCRIBE_FLAG_VOLATILE
The LE Audio implementations do not really support bonding yet,
and removing subs on disconnect is the most effective (and correct)
way of ensuring that we do not subscribe more than once when we
re-discover after reconnection.

The broadcast assistant and the media control client does not
support multiple connections as of this commit, so they needed
special treatment. In the case that we do discovery on multiple
ACL connections, it is important that the existing subscriptions
are removed correctly by calling bt_gatt_unsubscribe.

In order to implement this change properly on some of the clients,
thet had no proper connection references or support
for clearing the data on disconnects, they had to be updated
as well.

The csip_notify.sh test has been disabled, as that expected a
notification in the client, but since this commit removes that
(until bonding is properly supported in the clients), then the
test will fail.

f3b0a8f478 Bluetooth: Audio: Fix broadcast assistant recv state pointer value
When reporting a receive state to the upper layers, the broadcast
assistant should report NULL if there is not a receive state
active. The "activeness" of a receive state is determined by
the length of the characteristic - If it is 0 then there
is no receive state active.

e458f5aae6 Bluetooth: Use Zephyr standard log system instead of bluetooth/common/log
The `bluetooth/common/log.h` and `bluetooth/common/log.c` files have been
removed. Files that were using them have been updated to use
`zephyr/logging/log.h` instead.

Those replacement have been done consequently:
- `/BT_DBG/LOG_DBG/`
- `/BT_ERR/LOG_ERR/`
- `/BT_WARN/LOG_WRN/`
- `/BT_INFO/LOG_INF/`
- `/BT_HEXDUMP_DBG/LOG_HEXDUMP_DBG/`
- `/BT_DBG_OBJ_ID/LOG_DBG_OBJ_ID/`

Also, some files were relying on the `common/log.h` include to include
`zephyr/bluetooth/hci.h`, in those cases the include of `hci.h` has
been added.

For files that were including `common/log.h` but not using any logs,
the include has been removed and not replaced.
