[chromium] Add acceleration ratios for the deltas to WebMouseWheelEvents.
https://bugs.webkit.org/show_bug.cgi?id=109611
The deltas in mousewheel events generated by track can be accelerated (e.g. when
scrolling repeatedly). Keep track of the ratio of the acceleration since that is
useful for some tasks (e.g. overflow navigation gesture).
