Ability to customize OPTIONS auto-response and its middleware per group

[samdark]

What

We need ability to customize OPTIONS auto-response per group:

$group = Group::create('/v1')
  ->withAutoOptions(MyCustomMiddleware::class, CorsMiddleware::class)
  ->routes(...)

How

A group should add new OPTIONS route with the middleware specified for each unique pattern.

Why?

The use case is the following.

1. We have an API with /v1/** and /v2/** endpoint groups and want to apply different CORS middleware to both.
2. The rest of URLs should respond with default OPTIONS with all the methods available.

Additionally

Remove ability to disable auto-OPTIONS in router. Either it's sane defaults or using your own middleware.
