[Omnichannel] Setting `sendBoxTextWrap` via `createStyleSet` is being ignored

Describe the bug

When setting sendBoxTextWrap in styleOptions, it works. The send box text box would become <textarea> (text wrap = multiline).

When setting sendBoxTextWrap in createStyleSet and set it through styleSet prop, it did not work. The send box still is <input> (single line = not text wrap).

Steps to reproduce

Use the following code to render Web Chat.

window.WebChat.renderWebChat(
  {
    directLine: window.WebChat.createDirectLine({ token }),
    styleSet: window.WebChat.createStyleSet({
      backgroundColor: 'orange',
      sendBoxTextWrap: true
    })
  },
  document.getElementById('webchat')
);

Expected behavior

It should render the background as orange. Plus, the send box should be <textarea>.

Additional context

Workaround could for now is to set both styleOptions and styleSet props. sendBoxTextWrap only need to pass to the styleOptions prop.

When fixing this issue, check if we are also doing it correctly for sendTimeout or other values that is not represented in CSS.

[Bug]

Start at the createStyleSet and renderWebChat entry points, comparing how styleOptions and the styleSet prop handle sendBoxTextWrap and other non-CSS values such as sendTimeout. Reproduce the issue with the provided example; done means the styleSet configuration renders the orange background and uses a textarea for the send box without requiring styleOptions.
