LibWeb: Implement CanvasRenderingContext2D.drawImage() closer to spec

Browse source 
Also add support for HTMLCanvasElement for the image parameter, leading
to replacing HTMLImageElement with the CanvasImageSource Variant type.

Also stub out the 'check the usability of the image argument' and 'is
not origin-clean' operations, while taking into consideration that these
can throw (and require DOM::ExceptionOr).
