alloy: views: mac: Add three-finger-swipe navigation gesture support

Browse Source 
This adds support for the three-finger-swipe navigation gesture with
Alloy/Views. The default implementation matches the Chrome runtime
and navigates the browser back/forward. We also add an Alloy/Views-
specific client callback in CefBrowserViewDelegate for optional
custom handling of the gesture event.
