476e7b3fa3 Bluetooth: Audio: Ensure that read callbacks can handle conn == NULL
The read callbacks may be called with conn == NULL if the device
does a local read of the attributes. This commit ensures that all
the read callbacks can handle the case where conn == NULL.

bf37784dea Bluetooth: PACS: Fix logical dead paths
In pac_notify and pac_notify_loc coverity found logical dead
paths since if both sink and source notify was disabled,
the functions would still be compiled, but would
never get past the default case.

This is not a real issue as the functions were never called
in that case, but to make coverity happy, and to prevent
any future issues where the functions may be called
incorrectly, the static functions are now fully guarded.

78a4b33e5c Bluetooth: audio: pacs: Add bt_pacs_set_available_contexts_for_conn
This adds the function that sets the available contexts value per
connection object so that API user can set different available contexts
per connection.
The lifetime of such overriden value is the same as connection lifetime,
so on reconnection or device reboot all devices return to having the
same available contexts value again.

Fixes: #64968

This fix allows PACS to notify bonded clients, that were disconnected

This fix also implements a defer work so to not block the bt rx
thread during auth callbacks. All other notify calls are for

69f7fd9cb2 Bluetooth: Audio: Rename bt_codec to bt_audio_codec_{cap, conf, data}
Rename the bt_codec struct to bt_audio_codec_conf or
to the new struct bt_audio_codec_cap.
Rename the bt_codec_data to bt_audio_codec_data.

The purpose of this is to split the codec specific configuration
and codec capabilities into seperate structs, as they do not
reflect the same values, or used for the same purpose.

This commit depends on the preset macros workings on either
type of struct (for now), but will be modified in future updates.

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.
