Fix scanning synchronized methods (#86427)

After #85810 we need to generate reflection metadata for owning types of static synchronized methods. Before that change, obtaining a RuntimeType for locking would obtain a reflection blocked type. We now need a named type and scanner must predict it. Found in Pri0 testing.
