BadKB: Rewrite BadKB extras on "new" OFW BadUSB structure

- Mainly, HID interface abstractions and porting all BadKB options to it
- Tying up some loose ends, some things still not ideal but good enough
- Can customize BLE MAC address when BLE Remember is enabled
- Added BLE_ID command, alias for BT_ID (OFW BadUSB calls everything BLE)
