Detect XR Support with JavaScript

The presence of navigator.xr signals that the browser supports the WebXR API and XR devices:

I really like using in for feature checking rather than if(navigator.xr), as simply invoking that could cause some initialization to take place. In future posts we'll explore identifying and connecting to different devices.
