[FL-1009, FL-1118] Better initialization sequence and V8 hardware support (#406)

* Interrupt manager: add memory barriers.
* ISRs: remove TIM17 dead code.
* API HAL Delay: rename initialization routine and move to API-HAL
* Main: move FURI initialization to the start.
* API HAL GPIO: drop CC1101 shenanigans, COMP inversion for new boards.
* IButton: migrate Cyfral and Metakom to RFID comp routine, make it compatible with new boards.
* RFID: Better keyboard handling and shutdown routines
