[FL-977] Internal Storage ()
* Add littlefs submodule
* Furi: add mutex in logging, fix issues with corrupted printf
* ApiHal: disable debug traces in ble glue
* App-loader: more logs
* Passport: fix invalid DolphinState usage
* ApiHal, linker script: flash API is now aware of free space, complete abstraction layer for storage
* Internal Storage: littlefs based storage services with key value API. Migrate dolphin state to new storage API.
