Message:

Editor: Fix layout support classes to be generated with a stable ID.

This fixes a bug reported in ​https://github.com/WordPress/gutenberg/issues/67308 related to the Interactivity API's client-side navigation feature by replacing the incrementally generated IDs with stable hashes derived from the block's layout style definition.

Fixes #62985.
Props darerodz.
