Inverse logic of persistent set and prevent use in jit (#38131)
Summary:
jit.ScriptModule deletes all the actual attributes but still uses the nn.Module implementation.
Since I don't know how to add this new set() to the ScriptModule, it is simpler to just raise a nice error for now.
I also reverted the logic so that an empty set() (which is always the case in a ScriptModule) means that everything is persistent.
cc zdevito should we open an issue to add this to the ScriptModule?
