Add chrome.bluetooth and chrome.bluetoothLowEnergy for android

I think the `instanceId` just a unique identifier for `Service`, `Characteristic`, and `Descriptor` among all founded devices because we cannot specify which device is the `Service/Characteristic/Descriptor` belongs to when using the `chrome.bluetoothLowEnergy.*`

`/org/bluez/hci0/dev_64_A3_CB_3A_87_60/service004b/char004c`, this is a sample `instanceId` of a characteristic in ChromeOS
