Add an emptyName prop to SelectInput

[tdeo]

Is your feature request related to a problem? Please describe.
I'd like to display a custom text when the empty entry is selected in a SelectInput, to inform the user about what the default behaviour will be

Describe the solution you'd like
I'd like to pass a emptyName prop to SelectInput the same way we can add emptyValue. Ideally, this could either be a String or a React component

Additional context
Not sure what props should the React Component (or arguments if the prop accepts a function) receive. Maybe the source ?
