Aim

fn main(mut array: [Field; 2], i: u32) {
    array[i] = 2;

    let array2 = [array, array];
    println(array2[i][i]);
}

Expected Behavior

The value of array2[i][i] to be printed

The application panicked (crashed).
Message:  internal error: entered unreachable code: Dynamic array should already be initialized

I was experimenting with an optimization to optimize array merges across if conditions using [array1, array2][cond as u32] but this bug prevents that.

fix(acir_gen): Nested dynamic array initialization (#5810)
4df53ad 
# Description

## Problem\*

Resolves #5782 

## Summary\*

We are using our recursive `initialize_array_inner` function to also
check whether the outer AcirValue we are trying to initialize is a
dynamic array. We should be able to initialize a new AcirValue::Array
with internal AcirValue::DynamicArray types.
