rust: sync: add const constructor for raw_spinlock_t

The abstractions for pr_*_ratelimited! need to construct a global
`struct ratelimit_state`, which contains a `raw_spinlock_t` field. Thus,
add a const constructor for the `raw_spinlock_t` type.

The SPINLOCK_OWNER_INIT constant isn't mirrored via a const helper
because bindgen generates a 'static mut' instead of a constant from the
pointer constant.,

The __ARCH_SPIN_LOCK_UNLOCKED constant cannot be translated by bindgen
because it's a define for a struct without type annotations, so it's
explicitly declared in Rust.
