…ore blocks

Related Gutenberg PR: WordPress/gutenberg#25220.

It aligns with the latest changes added by aristath to the Gutenberg project. As part of styles splitting for core blocks, there was a special pattern introduced for how style handles are named. Ideally, we would apply it to all blocks but there might be some backward compatibility considerations so I left the handling for non-core blocks unchanged.

Props aristath.
See #50328.
