React-aria-components Tooltip should have option to not create aria-describedby attr

Hi folks, thanks for the great library!

We're trying to use Tooltip in the Storybook codebase for our toolbar buttons, selects and toggles, which don't have a text label.

In these components, we're currently deploying a pattern where each has an aria-label and a tooltip. We alter their content to avoid redundant SR announcements. For instance,

• The Measure Tool's Toggle button has aria-label="Measure" and tooltip="Toggle measure"
• The Theme Tool's Select has aria-label="Theme" and tooltip="Select theme"

In some rare instances, we use aria-describedby to explain what feature a button controls, when we think there's reasonable doubt for SR users to not understand what it does.

Having the tooltip repeated in aria-describedby would create redundancy in SRs we test with, and would overwrite our own descriptions. Of course, we can and will filter the attribute out, but I feel like this warrants an option in the underlying hooks and a documentation explanation for when which approach is most appropriate.

Interesting idea, we probably face this too. I'll bring it up with the team. In the meantime, if you add a wrapper around your tooltip contents with aria-hidden, that should also do this. Then you shouldn't have to mess with the props.
