The OpenVR SDK has made some changes that we need since the last time it
was updated. Primarily, this is the addition of the method:
GetAppContainerFilePaths and a few other updates intended to allow the
SDK to work better in the AppContainer version of the WebXr device
process.

Some prototyping will still need to be done before this can actually be
achieved, but doing this first roll better enables that and sets up a
(hopefully) smaller diff if another roll is needed due to any issues
discovered during prototyping.
