* 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 * Ble: fix incorrect nvm buffer size Co-authored-by: あく <alleteam@gmail.com>
