text: Title: Add option to disable reset button in `gr.Slider`
  Body: - [x] I have searched to see if a similar issue already exists.
  
  I notice that a reset button has been added to slider components. That is nice, but what would be even better if you could add reset buttons for other components as well. For my workflow I specifically need reset buttons for (single-select) dropdown components and radio components.
