Adds a new abstract struct for unicast group that is
specific for CAP. The difference between this and the BAP
unicast group, is that the parameters are CAP streams and
thus ensuring that the streams in the group adhere to the
additional requirements that CAP has on top of BAP.
This also adds foreach functions for both CAP and BAP
to allow users to iterate on the streams in the
abstract groups.
Various samples, modules and tests have been updated
to use the CAP struct and API.

Add a selection of interval values that are suitable for BAP,
which will allow better coexistence between ISO and ACL,
for both broadcast and unicast. Some of these are defined
by the BAP spec, and some are defined by Zephyr, since they
do have a suggested value from BAP.
Samples and tests have been updated to use these new values.
Peripheral samples have also been updated with
CONFIG_BT_GAP_AUTO_UPDATE_CONN_PARAMS so that the connection
parameters from the centrals aren't updated to something else
shortly after.
The shell has also been updated to use the LE Audio (BAP) values
if audio is enabled, and the audio.conf file has disabled automatic
updating of the connection parameters as the peripheral, as we rarely
(if ever) want to do that.
Due to the connection interval change, CI hit an issue
with test_bass_broadcast_code in test_main_client_sync, where
the reading of the long receive state did not finish before we
attempted to do another procedure, so the function was updated to have
a retry.

The CCP API for the Call Control Profile works on top of the
TBS API, and will eventually replace parts of the TBS API.

The QoS structure is not related to a codec, but rather a
stream, and should thus not use the "Codec" name.
The BAP and ASCS specs refer to the QoS as
"QoS configuration" several places, so it is an obvious
choice for a name.
Since the structure is defined and used by BAP, the prefix
was changed from bt_audio to bt_bap.

Several samples used K_FOREVER when allocating buffers in the
system workqueue thread, which is prohibited.
The samples should rather retry later if TX fails.
This is not the ideal solution for the samples, but
fixes a bug. Ideally the samples would use a dedicated thread
to handle TX, instead of the system workqueue.

Update the includes for Bluetooth Audio samples so they
properly include what they use.
The includes are then used to determine which relevant APIs
to refer to in the READMEs.
Finally improve the naming and description of the samples
using the Profile names and role.

Since the CSIP API expects a set member struct for nearly all
functionality, the reference to the full set member (along with
the CAS specific CSIS) should be given to the application.

The bt_iso_chan_send function could take an optional
timestamp by using 0 as an indicator. The issue with
this approach was that a timestamp value of 0 is valid,
and could cause potential issue with syncing streams
in a group.
To fully support transmitting with and without timestamp,
bt_iso_chan_send_ts has been introduced, which is the only
function of the two (bt_iso_chan_send being the other) that
supports timestamps.
A new function, rather than adding a boolean to the existing,
was chosen as it simplifies the individual functions as well
as making it more explicit what the function does.
Since the bt_iso_chan_send function is used by LE audio, both
the BAP and CAP send functions have similarly been updated.
Likewise, all tests and samples have been updated to use the
updated function(s), and BT_ISO_TIMESTAMP_NONE has been
removed.

Add const prefix for service uuid and char uuid.
Since Service UUID and Char UUID should not change in the service
definition, they are most reasonably defined as rodata, also for
save some ram footprint.
The field `attr->user_data` type is `void *`, as this PR change
all Service UUID to rodata, so there must add (void *) to avoid warning.

Refactor the bt_audio_codec_cfg to use flat arrays to store
metadata and codec specific configurations.
The purpose of this is to make it easier to copy the data
between layers, but also to support non-LTV data for non-LC3
codec configurations.

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.

Add implementation of the Telephony and Media Audio Service, as well as
two sample applications.
tmap_central reflects a smartphone implementing the Unicast Media Sender
and Call Gateway TMAP roles.
tmap_peripheral reflects an earbud implementing the Unicast Media
Receiver and Call Terminal TMAP roles.
Upon connection, tmap_central starts an audio stream using CAP Initiator
APIs.
CCP, MCP and VCP are discovered and used to send example commands.
Future improvements: 2-earbud support, add TMAP Broadcast roles,
update with new CAP Acceptor/Commander APIs as they become available
