[roll] Roll fuchsia [lockdep] Add thread annotations to NullGuard

This CL annotates the NullGuard as a scoped capability that is
acquired on construction and released on destruction. This will
allow callers to use a NullGuard the same way they would use a
regular Guard.

Also replaces a hand-rolled NullGuard implementation in debug.cc.
