Continuing from #407, since we prefer issues over PRs.

Adding Skyrim VR support should be fairly easy - it's basically Skyrim SE but without ESLs - but if issues arise, testing and reproducing is going to be difficult to impossible, since none of us own VR headsets.

Sub-issues:

• Correctly handle sVrResourceArchiveList BSAs in Skyrim VR #534
• Skyrim VR INI file should be called SkyrimVR.ini #549
• Officially mark the VR games as supported #635
