[FL-2441] BLE add Power state, fix double connection (#1238)
* battery service: add power state charachteristic
* bt: update power state on charging / discharging events
* ble config: support only one connection
* bt: always update flow control characteristic
* bt: fix power state update
* bt: simplify updating power state
* bt: don't update flow control charachteristic
