[FL-1952] BLE bonding fix (#805)
* furi-hal-bt: add mutex guarding core2 state
* ble-glue: configure ble keys storage in SRAM2
* bt: add load and save ble keys in internal storage
* bt: improve work furi_hal_bt API
* bt: rework app_entry -> ble_glue
* bt: apply changes for f6 target
* desktop: remove furi check
* ble-glue: comment NVM in SRAM2 configuration
* FuriHal: fix flash controller state corruption, fix incorrect semaphore release, implement C1-C2 flash controller access according to spec. Gui: change logging level.
* Libs: better lfs integration with lfs_config.
* Ble: switch C2 NVM to RAM.
* FuriHalCrypto: ensure that core2 is alive before sending shci commands
