Subject: [PATCH] Editor: Register 'lock' attribute for every block on the
 server

Backports changes from https://github.com/WordPress/gutenberg/pull/40468.

The lock attribute needs to be supported by every block, but currently, it is only done on the client site. As a result, it was causing block rendered API requests to fail when blocks are locked.

Props mamaduka, peterwilsoncc.
See #55567.
