rust: add C FFI types to the prelude
Rust kernel code is supposed to use the custom mapping of C FFI types,
i.e. those from the `ffi` crate, rather than the ones coming from `core`.
Thus, to minimize mistakes and to simplify the code everywhere, just
provide them in the `kernel` prelude and ask in the Coding Guidelines
to use them directly, i.e. as a single segment path.
After this lands, we can start cleaning up the existing users.
Ideally, we would use something like Clippy's `disallowed-types` to
prevent the use of the `core` ones, but that one sees through aliases.

aliases first. - Miguel ]
