Subject: [PATCH] feat(cw-button): Add aria controls to CW trigger (#2303)

Add an ID to the CW spoiler input field to give aria-controls a handle on it. Pass that id to the CW trigger button. Modify text icon button component to accept aria controls id value. Add aria-expanded value to text icon button to indicate when it is expanded.
