The nrf53 pretick can be used with non-zero
`NRF_RTC_TIMER_USER_CHAN_COUNT` Kconfig option.
The nrf53 pretick requires just one RTC1 CC channel.
The nrf53 pretick handles also RTC1 and RTC0 both CCs and OVERFLOW
events by examination of events scheduled on them. The pretick is set
based on number of ticks to the closest event scheduled that can trigger
an interrupt.
Because the operation in `z_arm_on_enter_cpu_idle` hook would
take too much time with interrupts disabled, the
`z_arm_on_enter_cpu_idle_prepare` hook enabled by Kconfig option
`ARM_ON_ENTER_CPU_IDLE_PREPARE_HOOK` is used. It performs RTC0 and RTC1
examination, and sets pretick without interrupts being blocked.
The LDREX/STREX are leveraged to detect if exception took place
between start of `z_arm_on_enter_cpu_idle_prepare` and
`z_arm_on_enter_cpu_idle`. If exception has not been taken, the pretick
calculation can be trusted because source data could not changed and
too much time could not pass. Otherwise the sleep attempt is disallowed,
the idle will loop again and try later.
Prompt for `SOC_NRF53_RTC_PRETICK` Kconfig option allows to control
this option by an user and turn the feature off if necessary.

Introduce an optional hook to be called when the CPU is made idle.
If needed, this hook can be used to prepare data for upcoming
call to z_arm_on_enter_cpu_idle(). The main difference is that
z_arm_on_enter_cpu_idle_prepare() hook is called before interrupts
are disabled.

Add RTC pretick option that triggers HW activity one tick before and

This commit adds support for finding registered mcumgr command groups.
By default, supported command groups are local to the namespace where
they're registered. This api addition allows applications to get
reference to these supported command groups to deregister & re-register
them.
This adds scope for applications to support multiple implementations
of a command group alongside the default.

This PR adds a mechanism to avoid calling open() or close()
on pipes which are already opened or closed respectively.
This optimization can help simplify backends implementing
the modem_pipe API by avoiding duplicated boilerplate code.
The TTY backend test suite has been updated to match the
new behavior.

This commit adds a check to prevent attempting to reestablish
the PPP session if the carrier is down. Without this check,
the PPP FSM attempts and fails to establish a PPP session
twice before giving up. The behavior is not breaking anything,
but it is not desired.

Adds a very simple hello world test case for llext. The loadable
extension is built and then included as a binary array into the test
making it very easy to load, debug, and inspect. The extension is
built using the same toolchain as the base image by default.

Adds the linkable loadable extensions (llext) subsystem which provides
functionality for reading, parsing, and linking ELF encoded executable
code into a managed extension to the running elf base image.
A loader interface, and default buffer loader implementation,
make available to the llext subsystem the elf data. A simple management
API provide the ability to load and unload extensions as needed. A shell
interface for extension loading and unloading makes it easy to try.
Adds initial support for armv7 thumb built elfs with very specific
compiler flags.
