The stack will no longer implicitly set the data path
for ISO channel, and the responsibility for doing that is
now for the upper layers/applications.
This provides additional flexibility for the higher layers
as they can better control the values and timing of the data
path, as well as support removing and even reconfiguring the
data path at will.
This also removes some complexity from the stack.
This commit also fixed a inconsistency in the disconnected
handler. CIS for centrals as well as BIS were still valid
bt_iso_chan channels in the disconnected callback,
but CIS for peripherals were completely cleaned up at this
point. This issue is fixed by moving the disconnected callback
handling to before the code to cleanup the channel for
peripherals.
Since there is a difference in how you remove data paths
depending on the GAP role (central/peripheral), the
iso_info struct type has been expanded to be more
concise of which type of CIS it is.

There is a corner case that the channel is in disconnecting status,
due to there is a disconnect request sent from peer.
At this time, the channel is status is `BT_L2CAP_CONNECTED`. But it
has been removed from `conn->channels` by calling the function
`l2cap_br_remove_tx_cid`.
And the disconnect event is notified upper layer via the callback
`ops->disconnected`. The thread of the callback context is blocked
due to the the calling of `printk` in the callback function.
Then the pending lower priority thread, sending the data in this
l2cap channel, is activated. Then in the function
`bt_l2cap_br_send_cb`, a NULL pointer will be got according to the
given CID. And unexpected behavior happens when accessing a NULL
pointer, since the invalid channel pointer is not checked in
function `bt_l2cap_br_send_cb`.
Check the channel pointer after function `bt_l2cap_br_lookup_tx_cid`
called. If the channel pointer is invalid, return error code
`-ESHUTDOWN` directly.

Some GATT services and profiles define specific behavior
based on whether the remote device is bonded or not.
The internal function, bt_addr_le_is_bonded, is the
only function to do this, but it was kept internal,
and could thus not be used for those services
without including hci_core.h.
The function has been moved to the public API
so that application can determine if a remote
address is bonded or not, and has been renamed
to not use the bt_addr namespace, but rather the
bt_le.

Set the flag `L2CAP_FLAG_DISCONNECT_ACL` when result of the L2CAP

Add a l2cap packet sent out callback `l2cap_br_conn_rsp_sent_cb()`.

There is a case that if the local is a peripheral and a L2CAP server
with the security level 3，the mitm should be set to make sure the
security level can reach level 3.
But in current implementation, the MITM is not set because the MITM
of `Authentication_Requirements` parameter of remote is not set. And
the security level will be level 2 after the security pairing
procedure complete.
Add a function `bt_l2cap_br_get_max_sec_level` to
get the max level of the registered servers.

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.
