When possible re-use the already allocated RX node for notifications.
Store (retain) RX node and Link element on RX if NTF could occur.
Pass link element to LLCP (ull_cp_rx()) together with RX node.
New RX node type RETAIN introduced to signal retention
When no RX node is available allocate one and hold off TX on procedures
until such time that a node is available for NTF.
In case waiting for NTF buffer avail is needed, allocate and store TX
node to use for TX once NTF becomes available.
CIS Established (incl. timeout handling) is now handled entirely as a
specific event driven by ull_conn_iso - ie removal of procedure check
of cis->established and cis->expire, as this is doubling mechanism
in the conn_iso context.
Unit test and helpers updated to handle new node type.
Function ull_cp_release_ntf() was used only in unit test, so moved to
helper context.
Updating release_ntf to handle the fact that with piggy-backing in test
context the node used for NTF can be from two different memory pools

Update the unittests for feature exchange to use the new ZTEST API
Here we only update the feature exchange procedure. The remaining
unittests will be done in a next PR
Mocks, helper routines and the Unit Under Test are splitted out as
a library instead of adding them to the file list

Getting rid of TODOs that are fairly straight forward to resolve
* introduce role checks in ENC API
* Remove ASSERT on re-rx of LL_VERSION_IND, ignore instead
* in tests/.../ctrl_chmu: rename variable and initialize initial ch map
* in tests/.../mock_ctrl/util.c: Changing TODO into FYI
* in tests/.../helper_features.h update mask and remove TODO comment
* in ull_llcp_remote.c: re-order cases in proc_with_instant switch
* in ull_conn_upd.c: PARAM REQ only uses REJECT_EXT_IND
* in ull_llcp_common.c: in CENTRAL on rx of LL_MIN_USED_CHANNELS_IND
chose to do nothing re. channel map. Update unit test accordingly

Add a separate procedure context pool for remote initiated procedures.
Make it configurable in size by BT_CTLR_LLCP_REMOTE_PROC_CTX_BUF_NUM.
Fix all unit tests referring to the amount of free context buffers.

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
