Mark context consumers with PerformedWork effect on render (#12729)

* Mark new component types with PerformedWork effect * Don't do it for ForwardRef Since this has some overhead and ForwardRef is likely going to be used around context, let's skip it. We don't highlight ForwardRef alone in DevTools anyway.
