<Listbox.Trigger> clear button, provide isSemantic prop

# Feature request
## Is your feature request related to a problem?
My problem is due to global styles with the clear button in the listbox trigger ``.

## Describe the solution you'd like
We could use the `` instead of the styled component, or provide a way to make it use `` with correct a11y semantics.

## Describe alternatives you've considered
- Alternative right now is to override the global css in consuming app

## Additional context

Start in the source folder for `Listbox.Trigger` and inspect how the clear control is rendered (currently styled as a button). Trace which props flow into that render path and add support for a semantic toggle so consumers can opt out of button semantics/styling behavior. Check Listbox usage docs or examples to add the new usage pattern, then run the Listbox component tests or demos to confirm the clear control is rendered with the expected element/semantics.
