rust: sync: atomic: Add generic atomics
To provide using LKMM atomics for Rust code, a generic `Atomic<T>` is
added, currently `T` needs to be Send + Copy because these are the
straightforward usages and all basic types support this.
Implement `AtomicType` for `i32` and `i64`, and so far only basic
operations load() and store() are introduced.
