[Bug 21969] [Custom]: add attributeChangedCallback to the set of prototype callbacks

https://www.w3.org/Bugs/Public/show_bug.cgi?id=21969

--- Comment #12 from Olli Pettay <bugs@pettay.fi> ---
In Gecko we'd use internal ScriptRunners for stuff that needs to right after
some script-unsafe C++ code.

(I could note that it was especially some googlers who didn't want
MutationObserver callback to be called right after the mutation happened ;) 
similarly to what is proposed here.
Some of the performance concerns are valid also in this case.)
