Message:

REST API: Preserve unknown, respect null in server-side block rendering.

• Skips validation where there is no attribute definition, but keeps the attribute value. Previously, the attribute would be omitted from the attributes passed to render_callback. Notably, this resolves an issue where render_callback cannot receive a block's align and customClassName attribute values, since these are defined as a client-side filter.
• Validates null as a proper value in its own right. Previously, a client implementation of a block could track {"attribute":null} as an explicitly empty value, and the server would wrongly initiate defaulting behavior. The new behavior will now only populate a default value if the attribute is not defined at all, including when unset in its being invalid per the attribute schema.

Props aduth, noisysocks, youknowriad.
See #45145 for the patch, #45098 for the original ticket.
