Reshape forward dims

The goal of this MR is to be able to forwardDims this graph by constant folding it considering Shape as constant:

Here is a small animation of the simplification processus

Major modification

• Constant folding return a bool if it changed the graph
• Add more verbosity for debug mode with constantFolding and forwardDims methods
• ConstantFolding now has an arg constantShape to consider Shape As constant producer during folding process.
• forwardDims possess an arg shapeAsConstant to constantFold shape during dims propagation. (Allow to forwardDims for Reshape as we add a constant for the shape input)

TODO

• Update constant folding
• Add a recipe constant_shape_folding to fold shape
• Add a unit test
