Add api.HTMLElement* constructor data

What type of issue is this?

Missing compatibility data

What information was incorrect, unhelpful, or incomplete?

In https://github.com/mdn/browser-compat-data/pull/30349 we decided to not record HTMLElement* constructor data for now. We should add this data all at once, if we want to record it. It is a separate project, not a drive-by task.

The HTML specification added these HTML element constructors ca. 2016 to make them sub-classable for custom elements.

What browsers does this problem apply to, if applicable?

No response

What did you expect to see?

HTML element constructor keys.

Did you test this? If so, how?

Didn't test, the collector tests need to be fixed so we could collect this data all at once.

Can you link to any release notes, bugs, pull requests, or MDN pages related to this?

MDN content needs to decide if it wants content pages. Maybe mentioning the constructor in HTMLElement* interface pages is enough.

Do you have anything more you want to share?

Start by reviewing the decision in PR 30349 and the collector tests that the issue says need fixing. Determine the complete HTMLElement* constructor set and whether MDN content pages are needed; done means the collector can gather the data and the HTML element constructor keys are recorded consistently.
