feature #28294 [Messenger] Remove the "obscure" message subscriber configuration (sroze)
This PR was merged into the 4.2-dev branch. Discussion ---------- [Messenger] Remove the "obscure" message subscriber configuration | Q | A | ------------- | --- | Branch? | master | Bug fix? | no | New feature? | no | BC breaks? | yes | Deprecations? | no | Tests pass? | yes | Fixed tickets | ø | License | MIT | Doc PR | ø As described in #28275, all of the configuration can be done using yield and that we could remove the support for other ways (especially the obscure return `[['method', -10]]` syntax) as I believe this would clarify the configuration a lot.

* `EnvelopeItemInterface` doesn't extend `Serializable` anymore
9191
* The `handle` method of the `Symfony\Component\Messenger\Middleware\ValidationMiddleware` and `Symfony\Component\Messenger\Asynchronous\Middleware\SendMessageMiddleware` middlewares now requires an `Envelope` object to be given (because they implement the `EnvelopeAwareInterface`). When using these middleware with the provided `MessageBus`, you will not have to do anything. If you use the middlewares any other way, you can use `Envelope::wrap($message)` to create an envelope for your message.

* `MessageSubscriberInterface::getHandledMessages()` return value has changed. The value of an array item

needs to be an associative array or the method name.
