Block Editor: Fix WP_Block_Supports class compatibility with Gutenberg-provided class.

Browse Source 
When using WordPress trunk with Gutenberg master, there's an incompatibility causing 
the dynamic block generated classes to be omitted.
This commit refactors the block supports to fix that problem.

Props nosolosw.
Fixes #51606.

Built from https://develop.svn.wordpress.org/trunk@49310
