Scheduler ConnectInput and tensor filling with offset tests

Tests of Scheduler::connectInputs

The function Scheduler::connectInputs was added in aidge core in /aidge/aidge_core!4. This function use graph ordering to connect the inputs of a graphView to data Tensors passed in a Scheduler::forward.

• Add Scheduler::connectInputs tests

Test batch composition in a tensor

• Add test to fill tensor with offset (for batch composition)

Add registrar support for more DataTypes in tensor for backend_cpu

• Add more TensorImpl backend_cpu DataType coverage

Adapt the tensorImpl_cpu class constructor to respect the mother class TensorImpl

In this MR the constructor of TensorImpl_cpu is adapted to the new definition of TensorImpl. The TensorImpl mother class constructor was modified in /aidge/aidge_core!4. The mother class modification was meant to adapt the TensorImpl for backend opencv.

• Change number of elements for dims in TensorImpl
