Add `print_output` flag to `cairo-1` crate

[fmoletta]

When activating the print_output flag, the program output will be serialized and printed out by the CLI. This new serialization will recursively fetch arrays from memory and print them out instead of just showing the start and end addresses for the top-level array. For this example program:

use core::array::SpanTrait;
use core::array::ArrayTrait;

fn main() -> Array<Array<u32>> {
    let mut numbers = ArrayTrait::new();
    let mut numbers_a = ArrayTrait::new();
    let mut numbers_b = ArrayTrait::new();
    numbers_a.append(4_u32);
    numbers_a.append(3_u32);
    numbers_b.append(2_u32);
    numbers_b.append(1_u32);
    numbers.append(numbers_a);
    numbers.append(numbers_b);

    numbers
}

Current output (main branch), no flags:

Return values : [5:0, 5:4]

New output, print_output flag:

Program Output : [[4 3] [2 1]]

No output will be shown if print_output is not enabled (unless the program returns a panic result)

The decision to lock the output behind a cli flag is both to match the standard behaviour we have in the cairo-vm-cli crate for cairo 0 execution and to avoid having to execute the argument serialization logic when outputs are not needed
