The `audio init` should only initialize the audio (BAP)
stack. Furthermore, given that the `bt init` may do more
than just calling `bt_enable` it is generally for the best,
and more future proof, to let that command be the exclusive
way of calling `bt_enable` in the shell.

It was possible to enter a state where setting the QoS
for a source stream after having released a sink stream
as the unicast client would cause a segmentation error.
This issue is related to how the unicast shell is using
the unicast group.
A fix has been added for it, and a check for
whether or not `audio init` (to register the needed
callback) has been added. This check has also been added
for the broadcast sink.

This refactors how the BAP broadcast source handles the
extended and periodic advertising.
First it removes the start and stop of the extended
advertising, and instead expects the application
(or upper layers) to do this.
Second it exposes API functions to get the
necessary advertising data from BAP (service data and
the BASE), which the upper layers will then also
be responsible for setting and updating.

When the PA sync is lost, we clear the received_base so
that once we resync to the PA, we get the BASE again.
This is to make it easier to decode and use the BASE again
if the sync was lost, as the previous BASE may have
been printed a long time before.

This removes the callbacks from capabilities. The callbacks are used for
unicast server role only, while the capabilities are used for the
broadcast sink role as well. Thus the callbacks can be removed as there
is another bt_audio_unicast_server_cb API that is specific for unicast
server role.

Remove the support for caching ASEs on release.
This is mainly due to the 2-stage design in Zephyr: We
have the bt_audio_stream and the bt_audio_ep, where the
the latter represents an ASE in most cases.
However, once the endpoint goes into the codec configured
state, then a stream must be bound to it. This would be fine
(although a stream is technically not established at this point),
except that a stream is also, for unicast, specified for a
specific ACL. Once the ACL disconnects, the stream technically
becomes invalid, and if the stream is invalid, so is the endpoint.
Based on that, there's no reason (or even option) to keep the
endpoint in a codec configured state, as it would not
have a valid stream associated with it.
If we want to support an ASE going into the codec
configured state on ASE release (or ACL disconnect),
the relationsship between ASEs and streams needs to
be redefined.

Add a new command, connect-name, which takes a string
as the single input and uses that to setup a scan filter
and connect to the first device that matches the name.
This command is thus basically shorthand for
bt scan-filter-set <name>
bt scan on
bt scan off
bt connect
bt scan-filter-clear-name
The idea of this command is to not only make it easier
find and connect to devices in a crowded environment,
but also to more easily connect to devices that changes
their advertised address.
The implementation is minimal as it uses existing
shell commands.

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.

The function will be used to update the RSI value. The returned value
can be later used in advertisement data for set identification. This
removes the need of specific bt_csis_advertise function so that the user
can call the API to generate new RSI once needed (e.g. on RPA change).
This allows the user to manage the advertisement data to fit it's needs.

This API now becomes a low-level API, in the sense that it should only be
used if the app developer knows what he is doing and wants to ensure a
ATT_MULTIPLE_HANDLE_VALUE_NTF PDU goes on-air.
For the other 99% of use cases, `bt_gatt_notify` should instead be used, as
it will automatically upgrade to ATT_MULTIPLE_HANDLE_VALUE_NTF when
possible.
One can disable the batching of notifications when using `bt_gatt_notify`
by setting CONFIG_BT_GATT_NOTIFY_MULTIPLE_FLUSH_MS=0 .

Modify how the ISO channels are allocated for the audio streams,
as well as how the CIG is allocated for the unicast group.
This fixes an issue where the unicast group could not be
fully allocated before _after_ the bt_audio_streams had been
configured by bt_audio_stream_config, thus making it impossible
to create a unicast group before the connections have been established.
This leaves us with 3 basic data types:
1) Streams allocated by the application
2) Endpoints that represent ASEs
3) Audio_iso which is used to couple streams and ISO channels.
The Unicast Group for the unicast client will now have the same
lifetime as the ISO CIG for the central.
