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

jyasskin has just created a new issue for 
https://github.com/WebBluetoothCG/web-bluetooth:

== Say what to do when the system has no Bluetooth adapter or it's 
off. ==
We need to specify whether `navigator.bluetooth` simply doesn't exist,
 or `navigator.bluetooth.requestDevice()` rejects its promise (with 
`NotSupportedError`?), or if it's detectable some other way 
(`navigator.bluetooth.enabled`?). If the adapter is turned off after 
the user gets a device, should that be a `NotSupportedError` or a 
`NetworkError` (simulating that the device went out of range)?

See https://github.com/WebBluetoothCG/web-bluetooth/issues/127
