* 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
