[css-ui] Standardize tooltip styling and expose as `::tooltip`

**Edit:** [Resolved](https://github.com/w3c/csswg-drafts/issues/8930#issuecomment-1644333441) to add to spec on Jul 20, 2023 ---- Now that popover and anchor positioning are moving forwards, I wonder if it’s time to re-examine standardizing tooltip styling and adding a `::tooltip` pseudo-element so that authors can customize it. ## History - The earliest such proposal appears to be [Tantek’s from April 2000](https://lists.w3.org/Archives/Public/www-style/2000Apr/0014.html).
