commit b0e5777b6203aaebf30596ba76c424626ae4a720

Rename XRDevicePose to XRViewerPose

Update blink XR code files to rename XRDevicePose to XRViewerPose and
XRFrame.getDevicePose to XRFrame.getViewerPose.
This is one of several changes required to make Chromium conform to the latest
version of the web XR API standards, which are at:
https://github.com/immersive-web/webxr/blob/master/explainer.md#appendix-b-proposed-idl

This also required updating many test and expected test output files.
For example, global-interface-listing-expected.txt expected test output needs to
have interfaces and methods in alphabetical order.
