Handle Intermediate tensors within the sketch

    - Intermediate tensor info objects are not created by the user anymore. They're returned from create_op and reused. This will prevent allocation of the intermediate tensors in case of possible interface misuse.
    - Sketch object handles intermediate tensor info pointers inside its implementation class via a unique pointer vector
    - Conv2d operator is migrated into the new interface

Resolves: COMPMID-5776
