rust: sync: Make Guard::new() public

Since we added a `Lock::from_raw()` function previously, it makes sense
to also introduce an interface for creating a `Guard` from a reference
to a `Lock` for instances where we've derived the `Lock` from a raw
pointer and know that the lock is already acquired, there are such
usages in KMS API.

[Boqun: Add backquotes to type names, reformat the commit log, reword a
 bit on the usage of KMS API]
