Fix missing nRF CCM disable on connection event abort.
There can be a problem on nRF SoC for example when a S8
"encrypted" reception is aborted, and a 2M "cleartext"
reception starts; slow CCM (that is not stopped as part of
radio disable) will corrupt a fast received "cleartext" when
the same current free rx buffer is reused in the Controller.
This is not a problem when the connection being abort-ee is
on a faster PHY than the abort-er.

In current implementation, if the MITM flag of both sides is disabled,
the pairing method is incorrect.
Such as, the IOCAP of both sides is `display_yesorno`, the pairing
method is `PASSKEY_CONFIRM`. But actually, it should be `JUST_WORKS`
in this case.
Fix the issue by setting the pairing method to `JUST_WORKS` if the

This commit prevents ATT request APIs from blocking waiting on the
req_slab pool on the system work queue. The API will instead return
-ENOMEM.
This aligns with commit 05b16b971b, which
establishes that the GATT request APIs are non-blocking on the system
work queue. That commit makes GATT request APIs fail with -ENOMEM when
they fail to allocate a buffer for the ATT PDU on the system work queue.
There is no reason to make this distinction between the two resources,
and this makes the API more consistent.

After https://github.com/zephyrproject-rtos/zephyr/pull/72090,
`conn_tx_alloc` no longer blocks, and each buffer always has a
corresponding `bt_conn_tx` object. This eliminates the need to configure
the number of `bt_conn_tx` objects via `CONFIG_BT_CONN_TX_MAX`, since
every buffer now carries its own context even when no callback is used.
This commit deprecates `CONFIG_BT_CONN_TX_MAX` as it is no longer
necessary. Instead, `CONFIG_BT_BUF_ACL_TX_COUNT` is used to allocate
`bt_conn_tx` objects for outgoing ACL data. ZLL already uses
`CONFIG_BT_BUF_ACL_TX_COUNT` to configure the number of outgoing ACL
packets. With this change, modifying the packet count will automatically
adjust the number of corresponding contexts, preventing both context
starvatoin and underutilization.
This approach also aligns with ISO, where the number of `bt_conn_tx`
objects for outgoing ISOdata matches `CONFIG_BT_ISO_TX_BUF_COUNT`.

After https://github.com/zephyrproject-rtos/zephyr/pull/72090, each
packet to be sent (wether ACL or ISO data) has a corresponding
`bt_conn_tx` object, regardless of whether a callback is used.
This means that number of packets Host can send to Controller is limited
by the smaller of two values: ACL/ISO packets Controller can receive,
and the number of `bt_conn_tx` objects allocated by Host.
A mismatch between these numbers may lead to inefficient resource usage
on either Host or Controller side. If Host allocates fewer `bt_conn_tx`
objects than the number of buffers available on Controller for a given
data type, some Controller buffers may go unused. Conversely, if Host
allocates more `bt_conn_tx` objects than Controller can consume, the
excess objects remain unused.
This commit adds a check and issues a warning if the number of
`bt_conn_tx` objects is not aligned with the number of ACL/ISO buffers
reported by Controller via the LE Read Buffer Size v1 or v2 command.

Fix Central CIS offset calculation for dissimilar ACL and
ISO intervals in use.
Mayfly execution of `mfy_cig_offset_get()` could be after
"LLL Prepare" or before depending on whether a previous radio
event is being preempted or not, respectively; the
`conn->lll.event_counter` may not be pre-incremented.
This race condition is fixed by the fact that we use a
constant instant delta value now.
Dissimilar ACL and ISO intervals may lead to ACL overlapping
or be too close to ISO event, causing preemption; under this
case ACLs "LLL Prepare" would run after `mfy_cig_offset_get`
causing incorrect calculation of CIS offset without the fix.

structure as a constant CIS Create instant delta is now

One behavioral change that's done in favor of simplicity, is that where
there's previously been switch statements that could return an error for
unsupported packet types now simply pass any received packet unchanged to
lower layers of the controller (or the HCI transport). Handling this is
now the responsibility of the lower layers, however in practice hitting
such scenarios means that there's a mismatch between configured host and

- Add a public API function bt_rfcomm_send_rpn_cmd() to send RPN
