[FL-140] Core api dynamic records (#296)

* 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
* init records work
* try to implement record delete
* tests and flapp
* flapp subsystem
* new core functions to get app stat, simplify core code
* fix thread termination
* add strdup to core
* fix tests
* Refactoring: remove all unusued parts, update API usage, aggreagate API sources and headers, new record storage
* Refactoring: update furi record api usage, cleanup code
* Fix broken merge for freertos apps
* Core, Target: fix compilation warnings
* Drop firmware target local
* HAL Timebase, Power, Clock: semaphore guarded access to clock and power modes, better sleep mode.
* SD-Filesystem: wait for all deps to arrive before adding widget. Core, BLE: disable debug dump to serial.
* delete old app example-ipc
* delete old app fatfs list
* fix strobe app, add input header
* delete old display driver
* comment old app qr-code
* fix sd-card test, add forced widget update
* remove unused new core test
* increase heap to 128k
* comment and assert old core tests
* fix syntax
