Move API layer-only classes back from the shared static lib.

Since ContentBrowserClientQt::OverrideCreateWebContentsView now
takes care of using our Qt layer at runtime without relying on
the static RenderWidgetHostView::CreateViewForWidget, we can
now avoid linking this layer into the render process.
