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

[Alexandre Courbot]

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.
