Extend the execution order for the gradients if it used for clipping by
global norm. The gradient is extended by the max execution order where
the norm of the gradients will be calculated and used to update and
apply the gradients.
This is done while requesting the gradient itself at the first time as
the layer properties are finalized by then.
