Follow on to moving wheel_event_handlers to LayerTreeView
Through reading some code I discovered a potential issue in commit
ee0b6981de62e9a234d031eab793da8d7752197b
(https://codereview.chromium.org/1639363002)
I moved the callback to setting the wheel event handlers onto the
ChromeClient. It appears WebPagePopupImpl extends the EmptyChromeClient
and it should likely call the appropriate things on the layer tree view
it owns. Also added setTouchAction call since I think it should
be implemented.
