Handle resize corner layout entirely in the BrowserView (views) or BrowserWindow* (Mac)
and extend RenderViewHost with a concept of reserved contents rect, a place to show extra stuff,
such as Sidebar's mini tab UI.
sidebar UI implementation warranted this change (mini tabs UI and resize corner area for sidebar
contents).
TabContentsDelegate::GetRootWindowResizerRect() is no more, reserved contents area is now cached
in RenderWidgetHostView and updated upon view resize.
Views: BrowserView is responsible for the actual layout and reserved contents area update.
Mac: TabContentsController now manages all TabContents views in the main browser window to solve
two problems, first to prevent contents flickering during tab change not only for the page,
but for the sidebar and devtools contents too and, second, to monitor contents view frame changes
and update reserved contents area accordingly.
BUG=51084
TEST=All tests should pass, this is a refactoring CL.
