Controls: Fix options control types

[shilman]

Issue: #10947

What I did

Add documentation per #10947 request, FLATTEN the options control specification. This was actually a bug--something I'd started earlier but didn't finish.

Before:

  argTypes: {
    loadingState: {
      type: 'options',
      controlType: 'inline-radio',
      options: ['loading', 'error', 'ready'],
    },
  },

After:

  argTypes: {
    loadingState: {
      type: 'inline-radio',
      options: ['loading', 'error', 'ready'],
    },
  },
