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.

Since the PACS service is not part of the bt_bap API it should
not use the bt_bap prefix, and instead just be bt_pacs like the
rest of the PACS API.

Added option to set the PACS Characteristics through the bap API,
making PACS configuration runtime available. Source and Sink PAC, as
well as Source/Sink PAC Location is can be set through a register
function in the PACS 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.

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.

The TBS client callbacks are just informative so we

To support this for the long strings, the function

Added a fallback parameter to
bt_audio_codec_cfg_get_chan_allocation as absence of
channel allocation in BAP implicitly means Mono.
In the case that it is absent,
BT_AUDIO_LOCATION_MONO_AUDIO is the returned value.
This commit also fixes the implementation of
bt_audio_codec_cfg_get_frame_blocks_per_sdu as it only applies to
LC3 (as per the BAP spec). It also adds additional testing of it

Removes the CIS connection establishment from bt_bap_stream_start
and move the behavior to a new funciton bt_bap_stream_connect.
This has 2 advantages:
1) The behavior of bt_bap_stream_start is much more clear and more aligned
with the spec's behavior for the receiver start ready opcode.
2) It is possible to connect streams in both the enabling
and the QoS configured state with bt_bap_stream_connect as
per the spec. This allows us to pass additional PTS test cases.
To implement this new behavior, samples and tests have been updated.
The CAP Initiator implementation has also been updated
to accomodate for the change in BAP, but the CAP
initiator implementation should work the same for application, except
that it's now possible to do unicast start on ASEs in any order
(https://github.com/zephyrproject-rtos/zephyr/issues/72138).
