Support obj.clone(freeze: true) for freezing clone
This freezes the clone even if the receiver is not frozen. It is only for consistency with freeze: false not freezing the clone even if the receiver is frozen. Because Object#clone is now partially implemented in Ruby and not fully implemented in C, freeze: nil must be supported to provide the default behavior of only freezing the clone if the receiver is frozen. This requires modifying delegate and set, to set freeze: nil instead of freeze: true as the keyword parameter for initialize_clone. Those are the two libraries in stdlib that override initialize_clone. Implements [Feature #16175]
