Redesign profile settings using tabbed interface

[joedolson]

See also #51086, which proposes an API for tabbed settings usable by plug-ins. It would be nice to have a common tabbed settings framework, but I think it's more sensible to add it to core if it's being used by core.

The account profile page is a good candidate for breaking into tabbed sections: it's long, broken up by logical sections, and commonly extended, making it even longer.

In combination with #51086, I'd like to explore updating the profile screen.

Potential duplicate of #37934 where tabs were also proposed.
