Adds Loom mock implementations of the `lock_api::RawMutex` and `lock_api::RawRwLock` traits, as well as re-exports for the relevant concrete types, gated behind a `"lock_api"` feature. The `parking_lot` and `lock_api` crates provide a slightly different interface than the standard library interface to `Mutex` and `RwLock`, which can make them difficult or impossible to test using `sync::Mutex` and `sync::RwLock` mocks.

There was a problem hiding this comment.
I couldn't think of a cleaner way to satisfy this requirement, so I threw in a OnceCell.
