set_epsilon should not take a reference

	Layernorm_attributes&
	set_epsilon(std::shared_ptr<Tensor_attributes>& value) {
	inputs[Layernorm_attributes::input_names::EPSILON] = value;
	return *this;
	}

By taking a reference as parameter it would not be possible to pass rvalue, i.e. convenient code like below won't compile:

auto options = fe::graph::Rmsnorm_attributes()
    .set_epsilon(create_epsilon_tensor())

If the purpose is to avoid copy, the code should take const reference or use move semantics:

 Layernorm_attributes& 
 set_epsilon(std::shared_ptr<Tensor_attributes> value) { 
     inputs.emplace(Layernorm_attributes::input_names::EPSILON, std::move(value));
     return *this; 
 } 

There are also other cases need fixes:
