Splits up wm_xr.c into multiple files in their own folder: source/blender/windowmanager/xr. So this matches how the message bus and gizmo code have their own folder and files. This allows better structuring and should make the code scale better. I rather do this early on than to wait until we end up with a single, huge file. Also improves a bit how data is prepared and updated for drawing.
