Auto merge of #7972 - nox:codegen-heapsize, r=Ms2ger

Browse source 
Introduce DOMClass::heap_size_of

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.
