Mobile: only show dive computers in the Bluetooth connection list

And offer an option to show all devices in the settings. This is intentionally
not stored in the preferences as this should never be needed. We don't support
BT or BLE dive computers that we don't recognize. This is a last resort in case
a new firmware were to change the name or some other weird issue causes us not
to recognize a dive computer - and that should be fixed instead of worked
around.
