Complete event before setting BT_CONN_DISCONNECT which will then cause

Move auto-initiation of the peripheral connection parameter update,
this handling would only submit the delayed work with the timeout once
all other auto initiated procedures had completed. This behavior means
that the delay would not be set on when the connection was established
but instead relative to the previous procedures.
Based on the connection interval used, the instant(s) used, and the
number of auto procedures this delay becomes indeterminate.
Submit the work once connected, the constraint that existed in the
zephyr link layer earlier about requesting only one control procedure
at a time has been removed.
This also brings all the handling of the timeout work to the connection
state handling, which makes it easier to track this behavior in code.

Fixes issue #26900.
A controller may fragment an L2CAP SDUs in any way it sees fit,
including fragmenting the L2CAP header. Likewise, the receiving
controller may send the fragmented header as ACL data to the host.
The Zephyr host assumed that a `BT_ACL_START` was at least 2 bytes long,
and consequently read the two-byte length field from the buffer without
length checks.
This commit allows the `BT_ACL_START` to be less than two bytes,
updating the `conn->rx_len` onces the `BT_ACL_CONT` with the remaining
part of the length field has been received.

Fix host RX thread being deadlocked. The deadlock occurs because the
RX thread is stuck waiting in conn_tx_alloc with K_FOREVER but if the
connection is disconnected only the RX thread can unblock it in the
handling of the disconnect event.
This commit fixes this deadlock by splitting the processing of the
disconnected event into two parts.
The part needed to unblock the RX is to release resources held by
unack'ed TX packets and mark the connection state as not connected
anymore.
The RX thread waiting for free_tx fifo and the TX thread waiting for
the bt_dev.le.pkts semaphore will both check the connected state after
having acquired them and will abort if disconnected.
The rest of the processing will be handled at normal RX thread
priority like normal.
Move the bt_recv_prio handling to the Bluetooth host when the host
has defined its own RX thread (CONFIG_BT_RECV_IS_RX_THREAD=n).
If the HCI driver has the RX thread (CONFIG_BT_RECV_IS_RX_THREAD=y),
then the responsibility to call bt_recv and bt_recv_prio correctly
falls to the HCI driver.
The helper function bt_hci_evt_is_prio() is replaced with
bt_hci_evt_get_flags() so that the HCI driver can do this correctly.
This decision to replace was made so that existing HCI drivers
maintained out-of-tree will fail at compile time with the new system.

flags to be per advertising set and loop over advertising sets instead
of looking up legacy advertiser set or handle 0.

This patch introduces two major changes to the directed advertising
feature of the bluetooth host.
Deprecating the bt_conn_create_slave_le, and removing
bt_conn_le_create_slave which has never been released. This behaviour
has now been moved by to providing the peer direct address into the
advertising parameters.
Introducing directed advertising support for nonconnectable
directed extended advertising, both scannable and non-scannable.
A bug was also fixed in the the directed-adv command in the shell
when the argument "low" was given. The advertiseng parameter pointer
declared with BT_LE_ADV_CONN_DIR_LOW_DUTY was declared in a scope that
was no longer valid when it was used to start the advertiser.

Timeout is not added as a parameter to the BT_CONN_LE_CREATE_PARAM
