This PR adds support for checking the current owner of a lock. I consider this PR as a follow up to: #49249
We have a use case where we want to check if a given lock is active or not (if it's locked then we don't want to make a function call). Currently I can check if the lock I've created is owned by the process or not with the
isOwnedByCurrentProcessbut, if the lock is not active, the result will befalseand I cannot check if it's false because it's not locked, or its owned by another process.
