[roll] Roll fuchsia [zircon][rust] Add Rust SpscBuffer implementation

Ports the transactional, single-producer, single-consumer (SPSC) ring
buffer library from C++ to Rust. This implementation matches the C++
interface design, while leveraging Rust safety features to avoid unsafe
memory copying in `write` and `read` operations. It is meant to
interoperate transparently with the C++ version.
