[corlib] Improve RuntimeThread stub (#19782)
The only call site of RuntimeThread.InitializeThreadPoolThread() is in
ThreadPoolCallbackWrapper, and it needs to return a valid RuntimeThread
reference to prevent a NullReferenceException later on. So return
`new RuntimeThread (null)` instead of a null reference.
This fixes a wine-mono crash I have encountered in "ZUSI 3 - Aerosoft
Edition" (in ZusiDisplay), and it might fix mono bug #17994.
