[FL-3226] Deep Sleep Idle (#2569)

Browse Source 
* Improve RNG error handling
* Sync RTC shadow registers on Stop mode exit
* Implement working STOP2 mode
* Fix formatting
* FuriHal: disable SWD pins if debug is disabled
* Power: cleanup battery info view, handle zero current report from gauge
* Fbt: add command line argument for extra global defines
* FuriHal: cleanup debug defines in power and os, drop deep_insomnia counter.
* Add a setting to disable deep sleep
* Clean up furi_hal_power
* FuriHal,FapLoader,Debug: implement debug in stop mode, workaround resume in stop
* FuriHal: document OS and power subsystems debugging
* Furi: enable debug interface on crash
