script: Add remaining unique element event listeners (#38888)

This adds the remaining window as well as specific svg and animation
listeners. The test suite was erroring before, as we don't implement
`SVGAnimationElement` yet. Now, the test gracefully checks if the
interface exists before doing a lookup.

Part of #36258
