[Tooltip] Does not provide accessible tooltip role

[mathias-falkenberg]

Bug report

Current behavior

The Tooltip.Popup component renders with role='presentation'

Expected behavior

I would expect the tooltip to follow the WAI-ARIA Tooltip pattern, which states that the tooltip element should use the tooltip role.

Reproducible example

https://base-ui.com/react/components/tooltip

Base UI version

1.0.0-alpha.5

This falls under the same issue as #1420. The role would be added if aria-describedby gets added, but otherwise it's currently only a visual-only element

It seems a bit counter-intuitive to provide a 'Tooltip' component that is not a tooltip in the WAI-ARIA sense. Particularly when the library claims to adhere to the WAI-ARIA Authoring Practices...
