Auto merge of #25431 - warren-fisher:create-html-element, r=jdm

use create_html_element for HTMLAudioElement and HTMLImageElement

<!-- Please describe your changes on the following line: -->

Updated the Image and Audio constructors to use `create_html_element` via the Element::create method. This was done to meet these specifications of "Let (audio/image) be the result of **creating an element** given document, audio, and the HTML namespace." for [dom-image](https://html.spec.whatwg.org/multipage/embedded-content.html#dom-image) and [dom-audio](https://html.spec.whatwg.org/multipage/media.html#dom-audio)
Not sure what _is_ is according to the [create-element guidelines](https://dom.spec.whatwg.org/#concept-create-element) so I left it as None copying from #25393. Also copied the ElementCreator and CustomElementCreationMode from #25393 as I do not know what they do.
