[FL-3051] Gauge initialization routine refactoring, new DataMemory layout, configuration update (#2887)

* FuriHal: refactor power gauge config

* Format sources and move gauge DM load to separate method

* FuriHal: bq27220 refactoring part 1

* Power: use SYSDWN battery status flag for system shutdown

* Libs: bq27220 read DM before write, fix incorrect shift

* FuriHal: cleanup gauge config, add flags, add ptr DM type, update symbols

* FuriHal: 2 stage gauge DM verification and update, better detection routine

* FuriHal: update gauge configuration, lower sleep current and deadband

* FuriHal: gauge and charger health reporting

* Lib: cleanup bq27220 sources

* FuriHal: correct documentation for furi_hal_power_is_shutdown_requested

* FuriHal: proper gauge config for f7
