Add show_progress prop to Upload Component to bring back upload progress animation

[freddyaboulton]

Description

Closes #7988

We want a custom progress animation for MultimodalTextbox than we do for the other components uploads. So I'm adding a show_progress prop to be able to better distinguish between the two cases.
