This method is given a DOMClass value and returns whether it derives from Self.
Interfaces with no descendants directly check whether the given DOMClass is the
same as their own.
Clarify some code in do_create_interface_objects
rval.get() is believed to be always null upon entering this function.
This assumption is verified by the added assertion.
It makes more sense to move the block of code that was moved inside
the if statement which is the only place where it can be initialized.
Fixes#7941.

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.

Refactor #[jstraceable] to #[derive(JSTraceable)]
fixes#6524. I had to make an additional change not mentioned in the ticket - adding the `#[feature]` to enable deriving custom traits but I assume that's expected at this time.

Implement Named constructors and the Image constructor for HTMLImageElement
I'm not sure if I like how I mostly just duplicated the code in CodegenRust.py, so that might need to be refactored.
Instead of just calling it Image, we might want to call it ConstructorImage, to make it clear that it's a constructor. Anyone have an opinion on that?
There seems to be a bug in the HTMLImageElement getter/setter as the value is 0 regardless of what I do. This seems to be unrelated to my commits, so I'll investigate that separately.

Accidentally fixes bugs about Document::createElementNS() where the
implementation of "validate and extract" used to check whether the local name
extracted from the qualified name was "xmlns" instead of the qualified name
itself.
