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.

a05a47573a Bluetooth: ATT: Internalize ATT PDU TX pool
Why?
- metadata is easier to manage as an array + index
  - less error-prone -> less memory-management bugs
- we can. because of the previous refactor
- PDU allocations are more predictable
- ATT buffer size can be optimized by app
- isolates ATT from the rest of the ACL users
  - decouples ATT PDU size from e.g. SMP w/ LESC

Drawbacks:
- higher memory usage
- kconfig change

The higher memory use is only temporary, as this will be followed-up
with more refactors that should bring it back down.

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.

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.
