There are multiple places where double buffer is used in controlers
code. This commit adds generic implementation of the double buffer.
It can be used in future in all places where the data structure is
in use.

Pushes all work done in the topic-ble-llcp branch into main branch
This is a refactoring of the LL control procedures; the refactored
control procedures are hidden behind a KConfig option and
per default disabled
Goal of the refactoring:
close issue Link Layer Control Procedure overhaul #15256
make it easier to add/update control procedures
Refactoring consists in principal of writing explicit state machines
for the control procedures.
To reduce the risk of regression errors unit-tests have been added
Following control procedures are implemented:
Connection update procedure
Channel map update procedure
Encryption procedure
Feature exchange procedure
Version exchange procedure
ACL termination procedure
Connection parameters request procedure
LE Ping procedure
Data Length Update procedure
PHY update procedure
Min. nr. Of channels used procedure
Constant Tone extension request procedure

The ticker `ticks_drift` is propagated via the ticker
elapsed callback, in order to provide necessary information
to correctly calculate total elapsed durations by states and
roles that use ticker extensions to mitigate scheduling
collisions by drifting within a permitted window.

ULL reference count is checked in ULL_LOW context to decide
if LLL events are pending, but the reference count can be
decremented by the ULL HIGH execution context which can
prevent the set `disabled_cb` function not being called due
to no pending event to produce the done events.
Fixed by checking the reference count in the ULL HIGH
execution context using a mayfly to schedule the check.

Move the implementation of scan trains after call to LLL
prepare, so that LLL prepare executes without any latency.
To increase radio utilization, LLL prepare should be

Avoid using sizeof to access ULL and LLL struct members.
Based on the alignment requirements of structures, due to
padding between structure members, use of sizeof of previous
struct member to access next struct member is incorrect.
Continue to use explicitly stored parent pointer to access
ULL context. Combine event header and ULL header so that
the parent pointer point directly to the combined ULL
struct.

Fix conn_cleanup to be performed in the event done. The
regression was introduced in
commit 5412f61ac6 ("Bluetooth: controller: Introduce
separate done memq").
Now that done event is handled asynchronously outside the
handling of the terminate node rx type, it is necessary that
terminate node rx type is generated after the done event.

The same code block for marking an object with
ull_disable_mark, stopping the ticker and then unmarking
the object appeared multiple places; often with a regression
bug where instead of unmarking it in case of error, it would
be "remarked".

Preserve the TX power set with the `BT_HCI_OP_VS_WRITE_TX_POWER_LEVEL`
command for advertising and scanning procedures. As the TX power is no
longer overwritten on procedure start, the TX powers can now be set
before starting the procedure. This eliminates the chance for the first
transmissions to use the default TX power instead of the request TX
power.
Similar changes are not made to the connection advertising powers as
changing the TX power for a connection to device A should not change
the TX power for a future connection to device B using the same
`struct lll_adv` instance.
