[VR] Enable mouse cursor

[Adam Jimenez]

Using the touch controllers to navigate the UI is incredibly fiddly.

Please enable the mouse cursor or make it an option for easier navigation.

Touch controllers interaction should be way less fiddly now. (Drag detection sensitivity was turned down.) Please try again and let us know if it’s still a problem? (Feel free to reopen if so.)

When I tried to implement a floating mouse, it turned out to be nearly impossible to do.

A gaze pointer is also being considered.
