servo: Merge #7972 - Introduce DOMClass::heap_size_of (from nox:codegen-heapsize); r=Ms2ger
It holds a function pointer to the HeapSizeOf::heap_size_of_children() implementation corresponding to that IDL interface. This removes the need for a clumsly TypeId-based match expression in the former heap_size_of_eventtarget() function.
