Add a new hook to allow custom buttons next to "Add new post" button

[siddiquesaad]

There's no way to add a personalized button next to the "Add New <Post Type>" button on the edit screen in WP-Admin. Sometimes, customization is needed, like adding an "Import" button to be programmatically added to a custom post type. It'll immensely help to add a do_action here:

if ( current_user_can( $post_type_object->cap->create_posts ) ) {
	echo ' <a href="' . esc_url( admin_url( $post_new_file ) ) . '" class="page-title-action">' . esc_html( $post_type_object->labels->add_new ) . '</a>';
}

Thanks

I recently encountered an issue where adding a button such as "Import" was impossible without JS manipulation (which is hackish). Adding this do_action will allow me and other users to dynamically add a button on the screen for custom post types.
