Summary [WebXR] Viewports don't get an initial value until getViewport is called

The base layer viewports are not properly computed until getViewports() is called. This seems sensible from the JavaScript POV, however it might cause issues in the underlying platforms if a carefully crafted WebXR example is created. If getViewport() is not ever called the viewports won't get a proper value and thus the underlying platforms would get 0x0 sized viewports which in some cases might cause issues.
