[FL-1795] BLE GAP refactoring (#694)
* 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
* app_ble: pairing configuration
* bt: display pin code
* bt: refactor battery service
* bt: refactor device info service
* bt: change advertise timer to freertos one
* bt: separate app_ble to hci and gap
* bt: increase max ble packet size
* gap: refactoring
* bt: refactor serial service
* bt: support f7 target
* bt: not blocking pin code show request
