Adds the hooks to print the import map, enqueued script modules and script module preloads.

Description

In classic themes, the script modules used by the blocks are not yet known when the wp_head actions is fired, so it needs to print everything in the footer.

public function add_hooks() {
	$position = wp_is_block_theme() ? 'wp_head' : 'wp_footer';
	add_action( $position, array( $this, 'print_import_map' ) );

	add_action( $position, array( $this, 'print_script_module_preloads' ) );
