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, something we do in the KMS API.

BTW - anyone else we're waiting for to get this pushed? Asking because I
realized something else I wanted to do was actually expose type aliases for
different types of Guard types, but wasn't sure if I should do that in this
series or a separate series

I left some comments on patch #1, with that resolved, I will pick up
these two patches and send a PR along with other locking patches
to tip tree, if all goes well, this will be in v6.14.
