Added define PDU_AC_EXT_AD_DATA_LEN_MAX, maximum AD data

Refactor PDU chaining implementation to add aux offset in
the aux pointer field in the parent PDU when duplicating
chain PDUs.
By adding the aux offsets in the ULL execution context the
LLL prepare execution in Extended and Periodic Advertising
does not need to have a O(n) while loop in LLL execution
context.
This will reduce CPU use in the highest priority ISR
compared to current implementation where chain PDUs where
duplicated in ULL execution context and aux offset populated
in LLL execution context.

Refactor the ull_adv_aux_hdr_set_clear function so that the

Fix missing offset adjust field assignment in the Periodic
Advertising's sync_info struct that is present in the
Extended Advertising PDU.
When the sync offset is equal or over 2.4576 seconds from
the Extended Advertising PDU, then the sync offset has to
be reduced by 2.4576 seconds and the offs_adjust flag be
set in the sync_info field.
This fixes a bug where Periodic Synchronization could not
be established for Periodic Advertisings with intervals
greater than 2.4576 seconds as the sync offset was
incorrect due to rollover in the 13-bit offset field.

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
