            'field'    => 'slug',
            'terms'    => array('simple')
        ),

    ),

The below code is fine, you just have to include the meta query to the end, so you can get the categories that have one or more simple product.

$cat_args = array(
    'tax_query' => array(
        'relation' => 'AND',
        array(
            'taxonomy' => 'product_cat',
            'hide_empty' => 0,
            'hierarchical' => 1,
            'orderby' => 'name',
            'order' => 'ASC',
            'child_of' => 0,
            'pad_counts' => true
        ),
        array(
            'taxonomy' => 'product_type',
            'field'    => 'slug',
            'terms'    => array('simple')
        ),
    ),
    'meta_query' => array(
        'relation' => 'AND',
        array(
            'key' => '_product_type',
            'value' => 'simple',
            'compare' => '='
        )
    ),
);
