[lion-select-rich]: Single option support lazy loaded

[palash2601]

Feature request

When there is only a single option available in the listbox of lion-select-rich, an attribute singleOption should be added invoker element so that desired styling can be defined by the extended component.

Also since it is a single option will be available, it should not open overlay which displays the option

@palash2601 thanks for your pull request 💪 Although the related pr is already merged, there are still a few things that need to be tackled (also see the comments on the pr):

• could you add some docs? Maybe a story that explains what it does.
• could you add a test that handles dynamically added options (support for lazily loaded options). For this, you could hook into addFormElement and removeFormElement.
• could you maybe change attr name to single-option?
• it's recommended to use this.formElements.length for checking the amount of children (since it is allowed to add more visual sibling elements)
• the rich-select was designed to closely mimic the native select. Maybe we can make this an opt-in flag that you enable by default on your extension layer?
