Subject: [PATCH] Fix new button appearance in already shown generic wxInfoBar

If the info bar is already shown, newly added buttons have to be relaid
out to appear correctly, so just add a call to Layout() in this case.

This makes the generic version work as the native GTK one, which already
handled this use case correctly.

Closes https://github.com/wxWidgets/wxWidgets/pull/1441

Closes #14120.
