dca085e155 bluetooth: controller: refactor node_rx_pdu for memory optimization
Generic node_rx_hdr struct contains data not used for done event, so this
pdu specific data is moved to node_rx_pdu to minimize memory usage for
MFIFO_done alloc.

This however calls for a considerable write-through replacing the generic
node_rx_hdr with node_rx_pdu when relevant and needed.

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.

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.

183370277b Bluetooth: controller: fixing slot reservation for connection setup
With introduction of refactored LLCP was also introduced an error
re. calculation of initial slot reservation in connection setups.

Due to this error a bigger slot was reserved, leading to failure due to
connection overlaps in multiple.sh test.
Also the removal of this 'overhead' in slot reservations calls for
bigger time-allowance for l2pcap_stress test.

79e6b0e0f6 includes: prefer <zephyr/kernel.h> over <zephyr/zephyr.h>
As of today <zephyr/zephyr.h> is 100% equivalent to <zephyr/kernel.h>.
This patch proposes to then include <zephyr/kernel.h> instead of
<zephyr/zephyr.h> since it is more clear that you are including the
Kernel APIs and (probably) nothing else. <zephyr/zephyr.h> sounds like a
catch-all header that may be confusing. Most applications need to
include a bunch of other things to compile, e.g. driver headers or
subsystem headers like BT, logging, etc.

The idea of a catch-all header in Zephyr is probably not feasible
anyway. Reason is that Zephyr is not a library, like it could be for
example `libpython`. Zephyr provides many utilities nowadays: a kernel,
drivers, subsystems, etc and things will likely grow. A catch-all header
would be massive, difficult to keep up-to-date. It is also likely that
an application will only build a small subset. Note that subsystem-level
headers may use a catch-all approach to make things easier, though.

NOTE: This patch is **NOT** removing the header, just removing its usage
in-tree. I'd advocate for its deprecation (add a #warning on it), but I
understand many people will have concerns.

f650fd99e0 Bluetooth: controller: Add CTE present bit to pdu_data
If the CTE is attached to data channel packet, the packet must
include information about CTE. The information is stored in
CTEInfo structure that is available in S1 byte of a packet.
Radio checks if the S1 byte is present by verification of
CTE present (CP) bit in byte S0.

The commit add these data to pdu_data structure declaration.
That allows to prepare packet before it is parsed and send
by Radio peripheral.
Besides that there added a new function ull_pdu_data_init that
initlializes fields in pdu_data object that are read only by
lower link layer. CP bit in S0 byte and content of S1 bytes
are examples of such fields.

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
