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.

922ac3c7c1 Bluetooth: Audio: Add missing error checks for calls to bt_gatt_subscribe
Several places the LE Audio clients called bt_gatt_subscribe without
checking the return value, which could cause some issues in the worst
case, and in the best case, cause some unexpected behavior.

Some implementations had a bit more updating to handle the new
behavior.

84fd596062 Bluetooth: audio: mcs: Offload notifications to system work queue
This implements the deferring of characteristic value notifications to
be sent from system work queue thread context. Notifications issued from
Bluetooth Rx thread might not be sent if there are no L2CAP Tx buffers
available, as the operation is non-blocking to prevent deadlock while
waiting for free buffers.
The same operation issued from other thread context is blocking,
meaning that the thread waits until L2CAP Tx buffers become available.
Thus it's guaranteed the notifications will be sent.

With this patch, the control point operations become blocking until the
control point response is sent. Meaning there might be only one
pending operation waiting for completition. This might be further
improved by queuing the operations if needed.

f2918b0109 Bluetooth: Audio: Fix MCC discover callback on reconnected issue
With BT_GATT_SUBSCRIBE_FLAG_NO_RESUB the MCC subscriptions would
be resent to the server on reconnection. Since this may trigger an
error, the error will trigger a call to the MCC discover complete
callback.

For MCP We can assume that the server stores the subscriptions if
we are bonded, and thus we can use BT_GATT_SUBSCRIBE_FLAG_NO_RESUB.

e80c70fd05 Bluetooth: Audio: Fix MCC disconnect issue
When MCC disconnected, it would memset the entire instance.
This causes issues, because the subscription parameters
would also be memset, causing the `notify` callback to
be set to NULL. If this was done as part of a disconnect,
the GATT layer would attempt to call the notify callback
as part of cleaning up the ACL, but if the callback was
set to NULL (from the memset) this caused a fatal error.

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.

0c04cf3c8e Bluetooth: Audio: Fix issue with NULL instance for MCC notifications
It was possible that on re-connect, the MCC implementation
would receive notifications when cur_mcs_inst was NULL.

This is partially caused by a bug in gatt.c, but can
and should also be handled in MCC.

This commit ensures that we do not compare handles
on notifications with a NULL instance.

This commit also ensures that subscribe_mcs_char_func
is not called outside the context of the discovery
procedure by setting the subscribe callback
to NULL.

79e6b0e0f6 includes: prefer <zephyr/kernel.h> over <zephyr/zephyr.h>
As of today <zephyr/zephyr.h> is 100% equivalent to <zephyr/kernel.h>.
This patch proposes to then include <zephyr/kernel.h> instead of
<zephyr/zephyr.h> since it is more clear that you are including the
Kernel APIs and (probably) nothing else. <zephyr/zephyr.h> sounds like a
catch-all header that may be confusing. Most applications need to
include a bunch of other things to compile, e.g. driver headers or
subsystem headers like BT, logging, etc.

The idea of a catch-all header in Zephyr is probably not feasible
anyway. Reason is that Zephyr is not a library, like it could be for
example `libpython`. Zephyr provides many utilities nowadays: a kernel,
drivers, subsystems, etc and things will likely grow. A catch-all header
would be massive, difficult to keep up-to-date. It is also likely that
an application will only build a small subset. Note that subsystem-level
headers may use a catch-all approach to make things easier, though.

NOTE: This patch is **NOT** removing the header, just removing its usage
in-tree. I'd advocate for its deprecation (add a #warning on it), but I
understand many people will have concerns.

0142bf9484 Bluetooth: Audio: MCC - serialized subscription after discovery
The media control client used to subscribe to GMCS characteristics as
the characteristics were discovered, in effect queuing ATT requests.

Since then, the ATT MTU exchange has become automatic, leading to
larger ATT MTUs and more discovered characteristics per ATT response,
which again lead to the client enqueuing more subscriptions and
running out of buffers, with discovery failing as a result.

This commit moves the subscription to GMCS characteristics to a
separate sequence, so that it happens serially after discovery, rather
than in parallel with the discovery.

- Remove separate discovery parameters for the characteristics - they
  are no longer needed.
- Add a subscription callback and a couple of subscription functions

The subscription for characteristics for the included OTS has not been
modified.  Only two of these are subscribed to, and doing that is
currently not a problem.  And I need to better understand the
interaction with OTS and how these subscriptipons are used.

- as a consequence, CMake files and Kconfig files updates are done in

- a macro for debug output of Object ID values has been (temporarily)

  to pass check_compliance
