The code was assigning a pointer to a scoped buffer to
an object outside that scope. This would cause the driver
would receive garbage instead of a well-formatted IE and
would likely reject the IE. This in turn caused CSL IE
not being included in enhanced ACKs (verified with
wireshark).

IEEE 802.15.4-2020 defines four possible values for Key Identifier Mode
field of the Auxiliary Security Header. The current ieee802154 driver
API only supports two of them: b00 and b01. This commit adds support for
the two remaining Key Identifier Mode values. It's done by replacing a
field that can only hold Key Index into a field that can holds a pointer
to the entire Key Identifier field.

Improves standard conformance of the IEEE802154_CONFIG_ENH_ACK_HEADER_IE
option and introduces certain "soft MAC" capabilities around header IEs:
* Introduces types and helpers that allow driver maintainers to
represent, parse, write and validate header IEs.
* Introduces helper functions to access non-aligned fields in header
IEs, namely element IDs.
Updates the only existing L2 and driver pair that uses
IEEE802154_CONFIG_ENH_ACK_HEADER_IE: OpenThread platform radio and nRF5
and improves header IE validation in the nRF5 driver.
This change should help further driver maintainers to support
OpenThread's CSL and vendor IE extensions. It is based on the rules
specified in RFC #61227.
It is also a precondition to generically support both, "soft MAC" and
"hard MAC", approaches to header IEs in the TSCH protocol, namely the
time synchronization IE.

"Sleeping" has a well defined meaning in Zephyr related to threading and
power management. This differs from OpenThread's definition:
- Deprecates the "SLEEP_TO_TX" capability as it is redundant and
conflicts with all of Zephyr's nomenclature, #61227, RFC 2863, Thread
standard and IEEE 802.15.4. This binds the API to an implementation
detail of OpenThread, instead. See #63670 for the agreed migration path.
- Renames the "SLEEP" event to "RX_OFF" which conforms to the
nomenclature in Zephyr, this API and IEEE 802.15.4.

OT does not have 64 bit timestamp support. This is a limitation of OT
and not of the IEEE 802.15.4 driver API. Therefore any workaround

adapatation layer.

Zephyr 64 bit timestamps into the OT adaptation layer.

The IEEE 802.15.4 API and networking subsystem were using several
inconsistent timestamp resolutions and types. This change defines all
timestamps with nanosecond resolution and reduces the number of
available types to represent timestamps to two:
* `struct net_ptp_time` for PTP timestamps
* `net_time_t` for all other high resolution timestamps
All timestamps (including PTP timestamps) are now referred to a
"virtual" local network subsystem clock source based on the well-defined
types above. It is the responsibility of network subsystem L2/driver
implementations (notably Ethernet and IEEE 802.15.4 L2 stacks) to ensure
consistency of all timestamps and radio timer values exposed by the
driver API to such a network subsystem uptime reference clock
independent of internal implementation details.
The "virtual" network clock source may be implemented based on arbitrary
hardware peripherals (e.g. a coarse low power RTC counter during sleep
time plus a high resolution/high precision radio timer while receiving
or sending). Such implementation details must be hidden from API
clients, as if the driver used a single high resolution clock source
instead.
For IEEE 802.15.4, whenever timestamps refer to packet send or receive
times, they are measured when the end of the IEEE 802.15.4 SFD (message
timestamp point) is present at the local antenna (reference plane).
Due to its limited range of ~290 years, net_time_t timestamps (and
therefore net_pkt timestamps and times) must not be used to represent
absolute points in time referred to an external epoch independent of
system uptime (e.g. UTC, TAI, PTP, NTP, ...).

The IEEE 802.15.4 stack defines radio API helpers that provide
simplified and encapsulated access to radio API features.
These helpers were missing the `_radio_` infix. This infix is introduced
to clearly distinguish between MAC and PHY concerns. While PHY features
may be shared between L2 implementations (including the functions
concerned here), this is not true for MAC features.

The method ieee802154_radio_handle_ack() does not belong to the
PHY/radio layer but to the L2 layer. It is a callback called from the
radio layer into the L2 layer and to be implemented by all L2 stacks.
This is the same pattern as is used for ieee802154_init(). The
'_radio_' infix in this function is therefore confusing and
conceptually wrong.
This change fixes the naming inconsistency and extensively documents
its rationale.
It is assumed that the change can be made without prior deprecation of the
existing method as in the rare cases where users have implemented custom
radio drivers these will break in obvious ways and can easily be fixed.
Nevertheless such a rename would not be justified on its own if it were
not for an important conceptual reason:
The renamed function represents a generic "inversion-of-control" pattern
which will become important in the TSCH context: It allows for clean
separation of concerns between the PHY/radio driver layer and the
MAC/L2 layer even in situations where the radio driver needs to be
involved for performance or deterministic timing reasons. This
"inversion-of-control" pattern can be applied to negotiate timing
sensitive reception and transmission windows, it let's the L2 layer
deterministically timestamp information elements just-in-time with
internal radio timer counter values, etc.

The RSSI value in net_pkt (net_pkt_cb_ieee802154.rssi) was used
inconsistently across drivers. Some drivers did cast a signed dBm value
directly to net_pkt's unsigned byte value. Others were assigning the
negative value of the signed dBm value and again others were offsetting
and stretching the signed dBm value linearly onto the full unsigned byte
range.
This change standardizes net_pkt's rssi attribute to represent RSSI on
the RX path as an unsigned integer ranging from 0 (–174 dBm) to 254 (80
dBm) and lets 255 represent an "unknown RSSI" (IEEE 802.15.4-2020,
section 6.16.2.8). On the TX path the rssi attribute will always be
zero. Out-of-range values will be truncated to max/min values.
The change also introduces conversion functions to and from signed dBm
values and introduces these consistently to all existing call sites. The
"unknown RSSI" value is represented as INT16_MIN in this case.
In some cases drivers had to be changed to calculate dBm values from
internal hardware specific representations.
The conversion functions are fully covered by unit tests.

The IEEE802154_2015 option is misleading, as it does not introduce full
802.15.4-2015 standard compliance but only random bits, plus it's
defined at the radio driver level, which brings yet another confusion.
Because of that, the option will be deprecated, and respective parts of
code that made use of it converted to use more specific configurations:
* nRF driver will now use CONFIG_NRF_802154_ENCRYPTION to specify
whether to compile in TX security
* net_pkt will only add extra 802.15.4 control block fields if
OpenThread is used, as they were solely used by this L2
* OpenThread radio layer will now use the OpenThread version to
determine whether to compile in TX security.

Most IEEE 802.15.4 drivers do not support promiscuous mode, some do.
There is a dedicated L2 flag to signal this capability to clients.
Unfortunately the IEEE 802.15.4 L2 stack does not announce this flag
even for drivers that correctly expose it in their HW capabilities.
Some clients (notably the OpenThread L2) even uses promiscuous mode
without checking whether the driver actually supports it.
This change lets the vanilla IEEE 802.15.4 L2 check the driver's
HW capabilities to announce promiscuous mode on its 'get_flags()'
interface if supported.
The OpenThread L2 uses a constant (potentially incorrect) response
to 'get_flags()'. Fixing the OpenThread L2 is out of scope of this
change. This change just introduces TODO messages to the OpenThread code
so that the OpenThread team may fix the issue (or delete the TODO if they
deem it irrelevant).
