Introduce a new API for barrier operations starting with a general
skeleton and the implementation for barrier_data_memory_fence_full().
Select a built-in or an arch-based implementation according to new
Kconfig symbols CONFIG_BARRIER_OPERATIONS_BUILTIN and
CONFIG_BARRIER_OPERATIONS_ARCH.
The built-in implementation falls back on the compiler built-in
function using __ATOMIC_SEQ_CST as it is done for the atomic APIs
already.

The encryption-only security level has been removed from the
spec, see IEEE 802.15.4-2020, 9.4.2.2 Security Level field.
The standard provides the following explanation (ibid):
"This security level is deprecated and shall not be used in
implementation compliant with this standard. Devices that
receive frames with security level 4 shall discard them, as
described in 9.2.4. The counter mode encryption and cipher
block chaining message authentication code (CCM) used allows
trivial changes to the underlaying encrypted data unless
data authenticity is provided, thus using data confidentiality
only is not useful. In the case of TSCH mode, security level 4
allows higher security level frames to be downgraded to
security level 4 frames."

Currently the insertion of an authentication tag requires a memcpy() call
and breaks encapsulation.
This change removes the need for memcpy() and improves the encapsulation
by calculating and reserving the required headspace early on while
keeping insertion where it belongs in the outgoing security procedure.
This is also a preparation for improved standard compliance of the
outgoing security procedure which is scheduled for a later commit.

The naming of variables and arguments containing the authentication
tag length was inconsistent:
* Naming inconsistency between header "length" vs. authtag "size"
in the same API calls
* "Tag" rather than "Auth[orization ]Tag" in external API calls
which is too generic from a compliance and readability viewpoint.
This is in preparation to zero-copy authentication support.
Almost all call sites will be subject to required structural changes
later on so no relevant git blame noise/history loss will be introduced
by this naming change in the long run.

Over time, some non-standard concepts and extensions were introduced
into the stack (in KConfig, in drivers, in the internal API and into the
implementation) which makes introduction of additional standard-
compliant extensions like TSCH (and others) unnecessarily difficult.
To introduce extensions like TSCH it is required for the IEEE 802.15.4
stack to become more structurally aligned with the standard again which
will be the focus of some of the upcoming preparatory changes.
One way to check and prove standard compliance is to reference the
standard from within the source code. This change therefore introduces
inline references to the IEEE 802.15.4-2020 standard wherever possible.
Deviations from the standard are documented with TODO or deprecation
labels to be addressed in future changes.
In the future, new code introduced to the IEEE 802.15.4 stack should
be documented and reviewed for standard-compliance to avoid further
divergence. Most importantly:
* MAC/PHY configuration (via net mgmt, radio API, devicetree or
KConfig) should always be directly linked to well-defined MAC/PHY
PIB attributes if visible to the MAC API or the end user.
* Net management/shell/radio API commands should have a documented
reference to the corresponding MLME action from the standard.

The BT_CTLR_DF_SUPPORTED KConfig was a wrapper for DF related features
set that are supported by Zephyr's BLE Controller. At the same time the
KConfig is used by Host in compound build to enable BT_DF. That makes
the whole thing a bit coupled with Zephyr's controller.
External implementations of controller must provide same feature set
as Zephyr's Controller or there will be an error during build.
The PR moves the Zephyr's Controller DF supported features set to
Kconfig.ll_sw_split, where it is included only when BT_LL_SW_SPLIT
is selected. BT_CTLR_DF_SUPPORTED is now a top DF_SUPPORTED KConfig
option that enables possibility to select actual DF features.
That allows to select individual set of DF features by any controller
implementation and makes possible to enable BT_DF and build selected
DF Host features.

two sample applications.
tmap_central reflects a smartphone implementing the Unicast Media Sender
and Call Gateway TMAP roles.
tmap_peripheral reflects an earbud implementing the Unicast Media
Receiver and Call Terminal TMAP roles.
Upon connection, tmap_central starts an audio stream using CAP Initiator

This patch modifies intel_adsp_ipc_is_complete function so it don't
report that IPC is completed when we are still waiting for ACK from
HOST.
This change will allow to solve the problem that occurs during the power
state transitions. Occasionally, the Application decides to enter the
power gating state after sending an IPC message, before receiving an ACK
from the HOST. This results in broken IPC communication when coming back
to Idle state.

The current approach of failing the build on ztest with no optimization
broke coverage builds, and generally raised some concerns about being
too aggressive.
Downgrade the error to a warning and rework the option to inhibit the
warning, while also dropping it automatically for POSIX (that are not
really affected by stack size) and coverage run (that always runs with
no optimization).
Will reconsider this down the road if we still see issues filed for the
tests broken with no optimization and no further tuning.
