Message:

Block Styles: Ensure unique classname generation for variations

This commit simplifies block style variation class name generation to ensure unique class names by replacing the hashing of block attributes in the block style variation class names with a call to wp_unique_id.

Doing so avoids potential for non-unique class names and conflicting styles when exact copies of a block are inserted via a repeated pattern.

Props aaronrobertshaw, martinkrcho, mukesh27, peterwilsoncc, ramonopoly.

Fixes #61877.
