Subject: [PATCH v2 0/2] rust: transmute: implement FromBytes and AsBytes
 for ()

This is going to be useful in Nova's GSP message handling, as some
messages are empty and we need to explicitly use an empty structure for
them.

If accepted, I would like to merge it through `drm-rust-next` so Nova
code can start using this feature quickly.
