Message:

Blocks: Introduce filter to allow easy addition of hooked blocks.

Introduce a hooked_block_types filter that allows easier conditional addition (or removal) of hooked blocks for a given anchor block and relative position.

function insert_shopping_cart_hooked_block( $hooked_blocks, $position, $anchor_block, $context ) {
        if ( 'after' === $position && 'core/navigation' === $anchor_block && /** $context is header template part **/ ) {
                $hooked_blocks[] = 'mycommerce/shopping-cart';
        }
        return $hooked_blocks;
}
add_filter( 'hooked_block_types', 'insert_shopping_cart_hooked_block', 10, 4 );

Props gziolo, nerrad, dmsnell, ndiego.
Fixes #59424.
