[Cairo 1] Add flag to append return values to output segment when not running in proof_mode

[fmoletta]

• Adds the flag append_return_values to both the CLI and Cairo1RunConfig struct.
• Enabling flag will add the output builtin and the necessary instructions to append the return values to the output builtin's memory segment.
