Move WebVRServiceCallback registration to a cross-platform location

The WebVR service is registered through a callback function as a level
of indirection so that it can be implemented in chrome/browser, but
consumed by component.  This callback function needs to be set early
during process startup.

Desktop WebVR support is starting to land (behind a flag) so we need to
move registration from the current Android-specific location to
somewhere cross-platform.
