[FR] Provide Twig Method to Add to End Body

[davist11]

The css and js Twig tags already exist, but it would be really cool if there were a generic tag to add any code/string before the </body> and didn't do any processing to the string being passed in. This is useful for stuff like modals, etc. This is kind of why the Twig Portal plugin was created, except you can choose where the contents gets output too. We solved this by creating a custom Twig function addToEndBody that hooks into EVENT_END_BODY, but it would be pretty cool to see this be a part of core.

public static function add(string $code)
{
    Event::on(
        View::class,
        View::EVENT_END_BODY,
        function(Event $e) use ($code) {
            echo $code;
        }
    );
}

Just added a new html tag, similar to the current css and js tags, but for arbitrary HTML, for Craft 3.5.

{% html %}
    <p>This will be placed right before the <code>&lt;/body&gt;</code> tag.</p>
{% endhtml %}

It will inject the HTML right before </body> by default, but you can change the position by adding at head or at beginBody to the end of the opening tag.

@brandonkelly would it be possible to include this change already to 3.4? I feel i would find a good use for it in my current project but 3.5 seems bit far away.

@piotrpog 3.5 is very close.
