Re: [web-bluetooth] Say what to do when the system has no Bluetooth adapter or it's off.

I believe `navigator.bluetooth.requestDevice` UA chooser should be the
 one responsible for communicating to the user the state of the 
Bluetooth Adapter:

- Bluetooth adapter doesn't exist. In that case rejects instantly 
properly the promise with some `BluetoothAdapterNotFoundError` error. 
Regarding privacy concern, it might be hard to avoid timing attacks 

- Bluetooth adapter is off. "Turn on Bluetooth" should be available 
right there in the chooser if possible and would trigger a new BT 
search when enabled. 
If user dismisses it, the promise would be rejected with some 
`BluetoothAdapterNotFoundError` error.
