Adds a Views::GetAnchorBoundsInScreen() method. This defaults to
GetBoundsInScreen() but can be overridden for views whose visual
bounds differ from their actual bounds. This is the case for toolbar
buttons on Touch (that provide larger hit targets than their visual
size).

This method is then used for the menus spawned by AppMenuButton and
ToolbarButton as well as BubbleDialogDelegate which allows these
specific menus and BubbleDialogDelegates in general to be better
aligned visually to their anchors.
