[PATCH RFC 2/4] rust: prelude: re-export `zerocopy::Immutable`

[SeungJong Ha via B4 Relay]

From: SeungJong Ha <engineer.jjh...@gmail.com>

`impl_transmute_via_zerocopy!` requires `Immutable` (no interior
mutability) alongside `FromBytes`/`IntoBytes`. Re-export it from the
prelude like the other two.
