Replace DeviceManager::GetDeviceChanges with a client interface.

Replace DeviceManager::GetDeviceChanges with a client interface.

Changes to the Mojo EDK mean that it is no longer necessary to prefer
always calling from the browser process to render process. Thus, we can
replace the awkward GetDeviceChanges method with a DeviceManagerClient
interface implemented by Blink's USB object.
