BLE: F3 integration (#260)

* BLE: working version
* BLE: cleanup
* BLE: update device description and DIS.
* BLE: explicitly take semaphore and configure CLK48, bt subsystem status, remove LPM.
* HAL: add missing api_hal_bt_is_alive symbol
* TODO about valuemutex
* duplicate f3-1 (f4) ioc from f3
* regenerate project
* use target dir for ble glue path
* update f4 from f3
