Decouples AcceptAndContentTypeMiddleware from ResponseManagerInterface

[TiMESPLiNTER]

This PR decouples AcceptAndContentTypeMiddleware from ResponseManagerInterface and ApiProblem. Therefor it makes it possible to use the AcceptAndContentTypeMiddleware as a standalone class without being dependent on the generic ResponseManagerInterface that serves many other concerns as well beside generating responses for this middleware and one is not forced to react with ApiProblems as response if something's wrong in the middleware.

Note: Some tests for the new classes are missing, naming too long as well for the new classes.

$responseManager = new ResponseManager(...);
$middlewareResponseManager = new AcceptAndContentTypeResponseManager($responseManager);

$middleware = new AcceptAndContentTypeMiddleware(
    $acceptNegotiator,
    $contentTypeNegotiator,
    $middlewareResponseManager
);

Please run composer fix:cs and composer test

Besides that, this is an opinionated library, which since version 3 is focused on API Problem.
Is there any explanation why i should merge it ones, the change requests would be resolved?

useless phpdoc, its already typesafe by design

[dominikzogg]

this is a BC, both arguments should be possible, if the old is given, @trigger_error with user deprecation

I think it would be great to move it out of this repository as I really want to use only the middleware but not the whole other stuff. I think the middleware really solves a common problem which not necessarily should lead to a generation of an ApiProblem. Of course if you say this is more an all-in-one closed-eco-system package I'll create an own repo and just publish a "fork" of the middleware there. And we can avoid adding additional complexity in this package. :-)

@TiMESPLiNTER the size of this package isn't that big, so all-in-one wouldn't be the first time i would choose. I think copy'n'paste of the middleware (project or in a separate library) if its the only thing you need. Probably it is the easier solution.

@healerz any opinion on this one?
