This reverts commit d5c01e1c, reversing
changes made to e878ce91.

- Remove underscore in 'MetaOperator_Op' for python when one was present
- remove the number-of-input option from a test where it was not removed

Change Pad 'borderType' type in constructor to pass it by copy instead of const reference as it is just an enum

Add missing include to Add.hpp

Add getOrderedNodes(reversed=false) method which produces
a topological order of the graph view (or of the reversed
graph view when reversed is true).
This order is also deterministic given the nodes set and
the ordered output nodes.
Cyclic graphs are handled by breaking back edges as declared
in the new setBackEdges() method of the Operator class.
The order is suitable for resolving constant propagation
of tensor types in one pass including for cyclic graphs
if back edges are declared correctly for operators.
It is also suitable for exporting to onnx graphs
which require a topological order of exported acyclic graphs.

Update operator ctor name from '{type}Op{Nb_dims}D' -> '{type}{Nb_dims}DOp'. For implification of export register + improve overall logic.

Add Memorize operator binding for constructing node as
aidge_core.Memorize(end_step: int, name: str = "").

Update Memorize Registrar parent class to shared_ptr
in order to share implementation with python.
