feat(anon-layout): [Auth/PM-17737] AnonLayout - Consolidate and extend max width control (#15362)

* PM-17737 - feat(anon-layout-width) - consolidate width setting to control title, subtitle, and content together for a unified UX. Removes all titleAreaMaxWidth usages and the titleAreaMaxWidth property entirely.

* PM-17737 - AnonLayout - consolidate stories into playground (w/ the exception of default icon story b/c I can't figure how to omit the icon conditionally).

* PM-17737 - AnonLayoutStories - show secondary content by default

* PM-17737 - Per PR feedback, adjust maxWidthClass logic to remove string concatenation as it can result in tailwind classes not being compiled and available at run time.

* PM-17737 - Per PR feedback, refactor stories to use configuration to generate all the scenarios so we can still track them via snapshots

* PM-17737 - Fix anon layout mdx reference

* PM-17737 - Make AnonLayoutMaxWidths singular

* PM-17737 - When inside of a max width container, the icon container needs explicit width to be able to scale viewbox icons that don't have defined heights / widths
