Enable Bluetooth stack logging from Developer Options UI Element

Browse Source 
The goal is to be able to enable different log levels for Bluetooth
stack logging from Developer Options in Settings. This is done by
creating a Bluetooth property which houses the current state of the log
level, adding the required UI elements and linking the two together.
