SubGhz: add subghz tx_from_file CLI cmd, major TX flow refactoring, various improvements and bug fixes (#3302)

Browse Source 
* SubGhz: add cmd CLI "subghz tx_from_file"
* SubGhz:  add sending raw.sub files
* SubGhz: add load custom preset
* SubGhz: remove unnecessary files
* SubGhz: change message
* SubGhz: fix printf formatting
* SubGhz: Cli refactoring code
* FuriHal: add furi_hal_subghz Tx Rx IDLE state switching test
* SubGhz: remove debug code, fix ext driver compilation
* SubGhz: cleanup code, move wait status routine to cc1101 driver
* SubGhz: proper pin mode transition in tx stop isr routine, proper DMA and ISR priorities, fix issue with async tx stuck
* SubGhz: simplify async tx stop flow, fix ISR ARR check condition race
* SubGhz: check ARR only when we transmitting
* SubGhz: check ARR only when we transmitting for ext cc1101
* SubGhz: lower ISR priorities to safe level
* SubGhz: proper gpio config, comments update
