00c5edd411 Bluetooth: controller: Fix LLCP enc. execution ctx
rp_enc_state_wait_ltk_reply() is executed in thread context, so
it is not allowed to move the encryption state machine forward.

Defer LTK reply handling to next prepare event by introducing a continue
state.

Update the unit test to reflect this, and remove the TODO that actually
said there was an issue in the first place.

22f73992b2 Bluetooth: Rework the HCI header set
In order to have clean, self-contained HCI headers that do not have any
dependencies towards the Host or any other part of the system (except
types), reorganize the headers in the following way:

- Split out the macros and structs from hci.h to a new hci_types.h
- Merge the existing hci_err.h into the new hci_types.h

Fixes #58214.

998512f59b Bluetooth: controller: use RX node piggy-back for NTF when possible
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

e458f5aae6 Bluetooth: Use Zephyr standard log system instead of bluetooth/common/log
The `bluetooth/common/log.h` and `bluetooth/common/log.c` files have been
removed. Files that were using them have been updated to use
`zephyr/logging/log.h` instead.

Those replacement have been done consequently:
- `/BT_DBG/LOG_DBG/`
- `/BT_ERR/LOG_ERR/`
- `/BT_WARN/LOG_WRN/`
- `/BT_INFO/LOG_INF/`
- `/BT_HEXDUMP_DBG/LOG_HEXDUMP_DBG/`
- `/BT_DBG_OBJ_ID/LOG_DBG_OBJ_ID/`

Also, some files were relying on the `common/log.h` include to include
`zephyr/bluetooth/hci.h`, in those cases the include of `hci.h` has
been added.

For files that were including `common/log.h` but not using any logs,
the include has been removed and not replaced.

f023b5f611 Bluetooth: controller: push topic branch to main
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
