[EGD-8208] Removed unused ping, added simple Async

Removed unused code: ping and stale messages
Detached UnicastSync send and sync part so that we would be able
to await for message in the code.
Added sys::Async to be able to handle situations where we want to
sync to the response, but after some time.
Fixed messages logging: for some reason demangling abi use caused
bad system behaviour

[EGD-8208] Fixed race condition on ring within call management

Now we get request for call and to end call in proper order

[EGD-8208] Removed unused confusing code

for numerous reasons this is bad

[MOS-111] Added missing refresh conditions

Added missing refresh conditions.

[EGD-8193] Proper system shutdown durign update

Made sure all system is deinitialized during update.
Currently there are two exceptions: service eink and service
desktop. There are some issues with them but it should be fixed
in the near future

[MOS-110] Statistics api for system

Gets data from freertos and prints on frequency change depending
if it's important. Gathering is not costly, printing is though.
For less intrusive checks I would rather disable names gathering
as in worst case scenario it hangs rtos context switching till
thread id is found.

[MOS-144] Fix Increased CPU usage

On the locked screen, while refreshing the screen,
the CPU woke up to the maximum frequency,
which resulted in an increased power consumption.

[MOS-114] Frequency scalling skip 12MHz Level

Skip 12MHz freq level in the scaller

[MOS-114] CPU frequency scalling improvements

Add minimal frequency ~4Mhz, more aggressive CPU freq
optimizations.

[EGD-8193] Proper system shutdown durign update

Made sure all services are deinitialized properly

[EGD-8138] Software closing procedure improved

Release of resources and closing of all unfinished
services and workers.

[EGD-8137] Fix system pre closure procedure

Added some services specific implementations of pre closure procedure.
If one request pre closre, all mesagges (except system ones) recieved
by service are ignored.

[EGD-8156] Fix cellular on system close whitelists

Service cellular is added to system close whitelists.
It prevents hard fault when cellular is blocked
on long command handler.

[EGD-8154] Added watchdog thread closure on system exit

Made sure that watchdog thread is properly closed while exiting OS.

[EGD-8129] Add atexit functionality

Added atexit functionality. All global destructors and functions
registered with atexit() should be called at program exit.
It was possbile to reuse original newlib implementation with
MALLOC_PROVIDED flag set.

Made sure logger destructructor is called as last one.

Due to mudita OS legacy, it was not possible to simply fix dependencies
in global objectes and hence there are neither global objects
destructors nor functions registered with atexit() called when exit()
is called.
Possibly it will be changed later.

[EGD-8131] Add Reboot/Poweroff for _platform_exit()

Add support for Reboot and Power off for the
_platform_exit code.

Add _platform_exit mode handle
