As mentioned in swiftlang/swift-package-manager#5532 (comment) there is a need to migrate some bits of Process to spm and in order to do that the Lock.lock and Lock.unlock are needed to be public

thanks @Overcot, since this is just a simple wrapper of NSLock, maybe we move it whole sale into SwiftPM Basics module?

Yes, i can do it. But would i need to remove the wrapper inside TSCBasic or leave it as it is?

I suggest we leave it in, and put a @available(*, deprecated) on top of it
