Android: Edge glow effect for history navigation
Shows the edge glow effect when further forward navigation is not
possible. There are three cases to consider: native pages, rendered
pages, and tab switcher:
- Native pages: uses android.widget.EdgeEffect (GlowView)
- Rendered pages: uses ui::OverscrollGlow on cc::Layer of WebContents'
native view
- Tab switcher: also ui::OverscrollGlow on cc::Layer of StackLayout's
SceneLayer
All the logic is behind a new class NavigationGlow.
