add disable_n_clicks prop to html components

[AnnMarieW]

As reported on the forum, components with event listeners can cause issues with screen readers.

This PR adds a disable_n_clicks prop to all html components, giving the ability to remove the event listener.

By default, n_clicks will be enabled on any html component that has an id. If n_clicks is not used in a callback for that component, the event listener can be removed by setting disable_n_clicks=True`

For example:

• No event listener:
  html.Div()
html.Div(id="my-id", disable_n_clicks=True)

• onClick event listener:
  html.Div(id="my-id")
