refactor(tvix/nix-compat/wire): move magic bytes to worker_protocol r/7874

`primitive.rs` implements reading and writing primitive (fixed-length)
types in the wire format, used in the the nix daemon protocol and NAR
format.

Move worker-protocol specific magic bytes to worker_protocol.rs (and
possibly further split there once needed)
