Editor: Add utility classnames back to blocks that have layout attributes specified.

Browse Source 
[https://github.com/WordPress/gutenberg/issues/38719 In 5.9 these utility classnames were removed], which removed the ability for theme/plugin authors to assign their own custom CSS related to specific layout selections. This was mostly related to the Button block.

This commit adds these classes dynamically based on attributes, rather than saving them to the serialized content.
