Enforce that the Python Root SimObject is instantiated only once. The C++ Root object already panics if more than one is created. This change avoids the need to track what the root object is, since it's available from Root.getInstance() (if it exists). It's now redundant to have the user pass the root object to functions like instantiate(), checkpoint(), and restoreCheckpoint(), so that arg is gone. Users who use configs/common/Simulate.py should not notice.
