Reland "libgestures_glue: send wheel resolution flag to gestures library"

This is a reland of 3b95e462

Original change's description:
> libgestures_glue: send wheel resolution flag to gestures library
> 
> If the wheel is high resolution, the gestures library can use that to
> provide more accurate (and, in the future, responsive) scrolling. See
> https://crrev.com/c/2037035 for the gestures library implementation.
> 
> TEST=With https://crrev.com/c/2037035 patched, connect a suitable mouse
>      (such as a Logitech Anywhere MX) and enable the "Mouse High
>      Resolution Scrolling" gesture property. Check that moving the wheel
>      by fractions of a notch scrolls the page slightly.
