[FL-667] Power saving: deep sleep in tickless state (#300)

* SYSTEM: tickless mode with deep sleep.
* Move FreeRTOS ticks to lptim2.
* API: move all sumbodules init routines to one place.
* Timebase: working lptim2 at tick source.
* API Timebase: lp-timer routines, timer access safe zones prediction and synchronization. 
* FreeRTOS: adjust configuration for tickless mode.
* NFC: support for tickless mode.
* API Timebase: improve tick error handling in IRQ. 
* Apploader: use insomnia mode to run applications.
* BLE: prevent sleep while core2 starting.
* HAL: nap while in insomnia mode.
