[Add] 'Operator::backend()' member function and move Tensor dependence from header to source file when possible in operator

- Change parent class from Operator to OperatorTensor
- Remove shared and not customed functions from operators
- Uniformize operators behaviour:
    - inputs are set to nullptr at initialization by default
    - parameters whose size can be computed at initialization are (FC, ConvDepthWise)
    - Many more checks in functions with AIDGE_THROW_OR_ABORT()
