Overview page for UI Events

[wbamberg]

Fixes #15756, which is part of #13761 (comment).

This PR:

• adds a new API overview page "UI Events"
• converts the "DOM Events" entry in groupdata to "UI Events" and fixes various errors
• updates the interface pages under that page so they get a link to this overview page in the sidebar

Some of the linked events are 404. Usually this is because we have the event under a different interface, but I think I have it right according to https://w3c.github.io/uievents/#event-types-list

• abort: I think this should be on Window, and we just don't seem to have it
• beforeinput and input: we have pages for these under HTMLElement but I think they should be under Element.
