Update for fixes and improvements to Steam controller inputs.

An update has gone out that changes the following:

• Changes the input mapping for Index controllers.
  
• Improvements to Vive and Windows Mixed Reality controller inputs.
  

More specifically with Index, the input scheme is properly mapped out to be consistent with other VR controllers such as Quest:

• The B Button is now used for right-clicking on Desktop.
  
• The trigger no longer has to be fully depressed when clicking on menu items or the desktop.
  
• The trackpad can now only scroll up and down, and has been tuned to prevent accidental scrolling when the user rests their thumb.
  
• Opening the menu is now assigned to either trackpad click or analog stick click.
  
• Changing seats is now accomplished by pressing up on the analog stick.
  
• Analog stick deadzone has been increased slightly to prevent accidental snap turns when clicking the stick.
  

This update also fixes the following

• Fixes an input bug causing any menu sliders to behave incorrectly depending on how the VR controller is rotated.
  
• Fix a crash that can happen on older GPUs when entering a host's room that's desktop streaming.
