RNA: disable undo on OperatorProperties and its subclasses.

Since these are temporary properties, changing them shouldn't cause
undo pushes. There already is a flag to disable that, but since each
operator inherits its own properties from the base, RNA define code
also had to be changed to allow inheriting the flag.
