Re: [web-bluetooth] Consider exposing whether a characteristic has notifications enabled.

Because there's only 1 physical Bluetooth connection, and only 1 bond,
 yes the two pages share the same CCC descriptor, unless the browser 
explicitly intercepts uses and makes it look like they're separate. 
Marcel Holtmann suggested that Bluetooth Core might eventually provide
 a way for controllers to pretend to be multiple devices, one per 
application, where they'd each get their own CCC descriptor, but 
that'll take a while to propagate through platform APIs.

The current spec does have a whole 
[`BluetoothRemoteGATTDescriptor`](https://webbluetoothcg.github.io/web-bluetooth/#bluetoothremotegattdescriptor)
 type for messing with device-defined descriptors. It's not 
implemented in Chromium yet, but it's in the queue, and could get done
 faster with concrete use cases.
