Vive/Index controllers unusable in OpenXR mode

Steps to reproduce:

• Create a shortcut to minecraft://mode/?OpenXR=true
• Launch the shortcut with SteamVR open and properly configured

• Try to select any menu option using your compatible SteamVR controllers

• Try to create a control profile to rectify the problem

Expected result:

• The controls autoconfigure or you're able to create a control profile

Actual Result:

• You are unable to do either of those things

Note: This occurs because Steam doesn't have access to the folder Minecraft is stored in because it's a protected folder. Adding native binding support for SteamVR controllers in Minecraft would fix this problem.
