bluetooth: Initial WebBluetooth & WebBluetoothError.

In three patches the initial mock implementation of bluetooth.requestDevice
is implemented across blink & content. This allows layout tests to specify the
data responses the mock implemented in content should return via
testRunner.SetBluetoothMockDataSet and call bluetooth.requestDevice with the
expected results.

crrev.com/650613005 blink::WebBluetooth & WebBluetoothError interfaces.
crrev.com/702593002 content::WebBluetoothImpl & testRunner.SetBluetoothMockDataSet.
crrev.com/686813003 blink::BluetoothDiscovery::requestDevice implemented.
