refactor(tvix/nix-compat/wire): express magics as u64 r/7875
This allows using read_u64, write_u64, which is a bit easier to juggle with. Also, update names to align with the nix codebase, which makes it easier to spot both the constant name as well as the value. Leave the ASCII interpretation as a comment afterwards.
