Update LLCP handling during PHY update and Data Length update to not
start the LL control procedure if the remote has already indicated that
the procedure is not supported.
This fulfills the following requirement from the BT Core Specification
(Core_v5.2, Vol 6, Part B, Section 4.6):
Except where explicitly stated elsewhere in this specification, if the
peer Link Layer has indicated either during a feature exchange procedure
or by responding with an LL_UNKNOWN_RSP PDU that it does not support a
procedure, then the Link Layer shall not use that procedure.
Re-use the connection parameter request handling for PHY and
data length update procedures.

Created unit tests for the encryption and decryption functions.
Tested with the peripheral and with central_hr samples.
Due to latency of CAUv3 when used as CCM inline accelerator
only one of the PDU can be encrypted/decrypted within an
bilateral exchange M->S + S->M in a connection event.
If the RXed PDU is encrypted, the TXed PDU must be empty
with More Data if there is data in the LLL queue.
The TXed PDU will be encrypted when an empty PDU is RXed.

Data transmission was paused when PHY update request control
PDU was enqueued in ULL. If there was pending data PDU in
ULL that was not enqueued towards LLL, this caused

Move the tx pause due to PHY update request/response being
enqueued to pre_tx_ack callback, this way all pending PDUs
in ULL is enqueued to LLL.

Fix infinite recursion in host-based bt_rand function. This would call
HCI LE Random Number command, which would in turn call bt_rand, causing
an infinite recursion.
bt_rand -> prng_reseed -> BT_HCI_OP_LE_RAND -> le_rand -> bt_rand
To solve this issue the controller should avoid doing calls into the
host, so all calls to bt_rand in the controller should be replaced with
a call to a controller function.

As a part of a ticker extension interface, it is now possible to specify
a slot_window when starting a ticker. When setting the
ticks_slot_window to a non-zero value, it is requested that the node
timeout is re-located to a position within the window, where the node
does not collide with other nodes - aligning to the end of the window.
The solution takes into consideration if a node has already been
updated with drift correction (e.g. ADV randomization), subtracting this
from the window.

generated_dts_board.h is pretty redundant and confusing as a name. Call

dts.h would be another option, but DTS stands for "devicetree source"

The replacement was done by grepping for 'generated_dts_board' and
'GENERATED_DTS_BOARD'.

Under race conditions it is possible that there is no call
to k_sem_give to the waiting k_sem_take in the ull_disable
function.
ull_disable function checks for reference count before
using a mayfly to schedule lll_disable, which in turn
would close requested currently active role event leading
to done event being propogated to ULL. Done event would
then call the set disabled_cb callback when the reference
count is zero, giving the semaphore to the waiting
k_sem_give in the ull_disable.
Under race conditions if the reference count reached zero
after the reference count check and before the disabled_cb
was assigned in the ull_disable function, then there are
chances that a k_sem_give is not called while ull_disable
proceeds to waiting using k_sem_take.

Fix controllers address check in cases of controller-based privacy.
When controller has been instructed by the host to use privacy
the controller should look up the peer identity address and generate
an address based on the local IRK. In the case where no match
is found or the local IRK is all zeroes the controller shall use
the fallback address. If the fallback address is not valid the
controller shall return invalid params.
This commit fixes these issues:
- Starting a private advertiser without valid random address set
but a valid local IRK exists. In this case the advertiser should
be able to advertise using the RPA regardless of a valid random
or public address.
- Starting a private advertiser with a fallback to the public
address type or an adveriser using public address does not
check if a valid public address exists. The host cannot
advertise with an all-zero public address.
