Move Set/GetNativeWindowProperty to the browser-side
BridgedNativeWidgetHostImpl. Also, change from using a NSDictionary
attached to the NSWindow to just using a std::map -- these properties
do not actually need to be attached to the NSWindow.

Move Set/RemoveAssociationForView and ReorderChildViews to the
browser side, because that's where the views::View hierarchy is
stored. Compute the appropriate NSView->rank map and then send that
to the BridgedNativeWidgetImpl (in the future, this will be a
handle->rank map, when crossing process boundaries).
