[FL-2809] Rework BLE key storage (#2154)

* bt: disconnect first on profile change
* bt keys: rework bt keys
* saved struct: add payload size getter to API
* bt: rework bt with new key storage API
* bt: add keys storage operation to bt API
* hid: save bt keys on sd card
* bt: add unit tests for key storage
* bt: working profile switch
* bt: cleanup
* bt hid: change keys storage path
