False positive in standard `*Observer` web APIs

[macarie]

Describe the bug

I believe callbacks for the *Observer category of web APIs should be treated like those for setTimeout and friends and not marked as untracked.

To Reproduce

const [signal] = createSignal(5);

new IntersectionObserver(() => console.log(signal()));
new MutationObserver(() => console.log(signal()));
new PerformanceObserver(() => console.log(signal()));
new ReportingObserver(() => console.log(signal()));
new ResizeObserver(() => console.log(signal()));

Expected behavior

Using signals in these kinds of callbacks should not generate a warning.
