706cfc211d samples: bluetooth: fixes tmap sample issues
- Added support for CAP_COMMANDER in configuration to allow tmap-cg
 and tmap-ums roles to be validated. For CG and UMR, CAP INITIATOR
 and CAP COMMANDER roles are mandatory. Without this support, config
 "CONFIG_BT_TMAP_CG_SUPPORTED" & "CONFIG_BT_TMAP_UMS_SUPPORTED" are
 not getting defined and function fail during "valid_tmap_role()".

- Replaced iso_pool user-data size from 8 to kconfig setting
 "CONFIG_BT_CONN_TX_USER_DATA_SIZE" to allow conn_iso_send()
 to success. Without it the user-data for iso_pool configured
 with value 8 but the kconfig "BT_CONN_TX_USER_DATA_SIZE" has
 default value as 16 causes conn_iso_send() function to fail.

- Updated audio_timer_timeout() with expected QoS interval value
 to send ISO_SDU at every 10msec instead of 1 sec. Without this sink
 device receiving null-sdu most of the time as ISO interval is 10ms
 and unicast-source keep sends SDU at every 1 sec.

2ab5882e0b Bluetooth: CAP: Add cap_unicast_group API
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.

9d4cc4b49b Bluetooth: BAP: Add a set of suggested intervals to use with BAP
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.

Remove the HCI command & event emulation layer for ECDH commands and

The existing BT_ECC Kconfig option stays, but now gets automatically

commit removes so many explicit assignments in prj.conf files.

dc97bbd35f Bluetooth: Audio: Rename bt_audio_codec_qos -> bt_bap_qos_cfg
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

eb22e1fc98 Bluetooth: TBS: Make GTBS mandatory
Any places that checked for GTBS is now always enabled
as GTBS is mandatory to support, and the Kconfig option
was removed.

Also removed a duplicate Kconfig option for TBS,
BT_TBS_SERVICE_COUNT, as it was unused.

The other Kconfig option BT_TBS_BEARER_COUNT is used
instead exclusively to set it if needed.

Since GTBS can now exist alone, it must also
support having its own calls and other values.
This means that the GTBS and TBS instances now share
the same underlying struct.

a4e43d013c Bluetooth: Samples: Use string printing functions for error codes
When developing Bluetooth applications, you typically run into some errors.
If you are an experienced Bluetooth developer, you would typically know
how to translate the error codes into string representations.
Others might not.

This commit to adds string printing of error codes for all
samples to make them more user-friendly.

Several formatting alternatives were considered. The chosen alternative
balances code readability and FLASH size (with and without string
printing).

Example output from the peripheral_hids sample when the
peer rejects pairing:

```
Bluetooth initialized
Bluetooth authentication callbacks registered.
Advertising successfully started
Connected 5E:67:02:D3:1C:DB (random)
Security failed: 5E:67:02:D3:1C:DB (random) \
level 1 err 6 BT_SECURITY_ERR_PAIR_NOT_ALLOWED
Disconnected from 5E:67:02:D3:1C:DB (random), \
reason 0x13 BT_HCI_ERR_REMOTE_USER_TERM_CONN
```

Other alternatives that were considered:

- Use of parantheses:
```
// strings enabled
Security failed: 5E:67:02:D3:1C:DB (random) level 1 \
err BT_SECURITY_ERR_PAIR_NOT_ALLOWED(6)
Disconnected from 5E:67:02:D3:1C:DB (random), reason \
BT_HCI_ERR_REMOTE_USER_TERM_CONN(0x13)
// strings disabled
Security failed: 5E:67:02:D3:1C:DB (random) level 1 err (6)
Disconnected from 5E:67:02:D3:1C:DB (random), reason (0x13)
```

- Spaces and parantheses:
```
// strings enabled
Security failed: 5E:67:02:D3:1C:DB (random) level 1 \
err BT_SECURITY_ERR_PAIR_NOT_ALLOWED (6)
Disconnected from 5E:67:02:D3:1C:DB (random), \
reason BT_HCI_ERR_REMOTE_USER_TERM_CONN (0x13)
// strings disabled
Security failed: 5E:67:02:D3:1C:DB (random) level 1 err  (6)
Disconnected from 5E:67:02:D3:1C:DB (random), reason  (0x13)
```

- Parantheses around everything:
```
// strings enabled
Security failed: 5E:67:02:D3:1C:DB (random) level 1 \
err (BT_SECURITY_ERR_PAIR_NOT_ALLOWED(6))
Disconnected from 5E:67:02:D3:1C:DB (random), \
reason (BT_HCI_ERR_REMOTE_USER_TERM_CONN(0x13))
// strings disabled
Security failed: 5E:67:02:D3:1C:DB (random) level 1 err ((6))
Disconnected from 5E:67:02:D3:1C:DB (random), reason ((0x13))
```

- Error code first, then string representation:
```
// strings enabled
Security failed: 5E:67:02:D3:1C:DB (random) level 1 \
err 6 (BT_SECURITY_ERR_PAIR_NOT_ALLOWED)
Disconnected from 5E:67:02:D3:1C:DB (random), reason \
0x13 (BT_HCI_ERR_REMOTE_USER_TERM_CONN)
// strings disabled
Security failed: 5E:67:02:D3:1C:DB (random) level 1 err 6 ()
Disconnected from 5E:67:02:D3:1C:DB (random), reason 0x13 ()
```

- Apostrophes around error printing:
```
// strings enabled
Security failed: 5E:67:02:D3:1C:DB (random) level 1 \
err "BT_SECURITY_ERR_PAIR_NOT_ALLOWED (6)"
Disconnected from 5E:67:02:D3:1C:DB (random), reason \
"BT_HCI_ERR_REMOTE_USER_TERM_CONN (0x13)"
// strings disabled
Security failed: 5E:67:02:D3:1C:DB (random) level 1 err " (6)"
Disconnected from 5E:67:02:D3:1C:DB (random), reason " (0x13)"

3e634268d6 Bluetooth: ISO: Introduce bt_iso_chan_send_ts
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.
