Feature: #92815 - Introduce ForwardResponse for extbase

Description

Since TYPO3 11.0, extbase controller actions can and should return PSR-7 compatible response objects. To allow the initiation of forwarding to another controller action class \TYPO3\CMS\Extbase\Http\ForwardResponse has been introduced.

Minimal example:

<?php

use Psr\Http\Message\ResponseInterface;
use TYPO3\CMS\Extbase\Mvc\Controller\ActionController;
use TYPO3\CMS\Extbase\Http\ForwardResponse;

class FooController extends ActionController
{
   public function listAction(): ResponseInterface
   {
        // do something

        return new ForwardResponse('show');
   }
}

Example that shows the full api:

<?php

use Psr\Http\Message\ResponseInterface;
use TYPO3\CMS\Extbase\Mvc\Controller\ActionController;
use TYPO3\CMS\Extbase\Http\ForwardResponse;

class FooController extends ActionController
{
   public function listAction(): ResponseInterface
   {
        // do something

        return (new ForwardResponse('show'))
            ->withControllerName('Bar')
            ->withExtensionName('Baz')
            ->withArguments(['foo' => 'bar'])
       ;
   }
}

Impact

Class \TYPO3\CMS\Extbase\Http\ForwardResponse allows users to initiate forwarding to other controller actions with a PSR-7 compatible response object.
