[FL-1722] BLE custom serial service (#685)
* ble: remove heart rate profile
* ble-glue: delete dead code
* ble-glue: dis refactoring
* ble-glue: add battery service
* broken ble_common refactoring
* ble-glue: advertise 128 bit service uid
* ble-glue: remove dead code
* ble: advertise service 16 bit uid depending on flipper color
* ble-glue: remove debug
* ble: intriduce serial service
* ble: serial over ble
* bt: serial echo server
* bt: serial service process indicate acknowledge
* bt: serial service event handler update
* bt: refactore battery service
* bt: add battery level apdate API
* power: update battery level on change
* bt: refactore device information service
