Add QBluetoothDeviceDiscoveryAgent::deviceUpdated signal

For iBeacons and such, it's normal to keep discovering indefinitely,
while the advertisement can sometimes carry changing payload data.
This signal helps keep the UI up-to-date.

Changed setManufacturerData to return a bool indicating whether the
data was really modified or not, to avoid sending deviceUpdated
in case it was not changed.

For convenience QBluetoothDeviceInfo::manufacturerData() was added.

WinRT and Apple platforms do not emit the new signal yet and relevant
TODO items were added.
