Fix class construction recursion issue in Lock on NativeAOT

- The `Monitor` type was being constructed due to the use of `Monitor.DebugBlockingScope`, added that to the initialization phase
- If necessary, an alternative may be to move `DebugBlockingScope` to be under `Lock`. Based on the comments the thread-static field is apparently bound-to in debugging scenarios.
- Fixes dotnet#94227
