`AllowNoHandlerMiddleware` adds a frame in the call stack but its concern should be handled by `HandleMessageMiddleware` to me, and `HandlerLocatorInterface::getHandler()` should not care about whether it's an error or not to not have a middleware (this makes it on par with `SenderLocator` in this regard.)

While working on the component, I found it hard to discover the meaning of the `Asynchronous` and `Enhancers` sub-namespaces. Now that I know the component better, I understand they're only classifying namespaces with no specific technical semantics.
I'd like to remove them to make the component easier to discover.
This PR introduces a few new semantic sub-namespaces instead.
From the changelog:
* Classes in the `Middleware\Enhancers` sub-namespace have been moved to the `Middleware` one
* Classes in the `Asynchronous\Routing` sub-namespace have been moved to the `Transport\Sender\Locator` sub-namespace
* The `Asynchronous/Middleware/SendMessageMiddleware` class has been moved to the `Middleware` namespace
* `SenderInterface` and `ChainSender` classes have been moved to the `Transport\Sender` sub-namespace
* `ReceiverInterface` and its implementations have been moved to the `Transport\Receiver` sub-namespace

When a deprecated option with default value was resolved (the first time it's called) in this case through a lazy evaluation, [the default resolution process](8398947c9c/src/Symfony/Component/OptionsResolver/OptionsResolver.php (L771-L773)) takes the resolved value and here should also trigger only if the option was provided by the user or is being called from a lazy evaluation, otherwise ignore.

This header is not supposed to ever be exposed to clients of the application, but a hack to transfer information within the symfony application. This bugfix makes it so that we also remove the header when no session is started and thus no decision has to be taken whether to overwrite the caching instructions or not.

This provides a convenient method to add `Link` headers to the current `Response` directly from the `Request` object.
It improves the developer experience and the discoverability of [the WebLink component](https://github.com/symfony/symfony-docs/pull/10309).
Usage:
```php
namespace App\Controller;
use Fig\Link\Link;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
class MyAction extends AbstractController
{
public function __invoke(Request $request): Response
{
$this->addLink($request, new Link('mercure', 'https://demo.mercure.rocks'));
return $this->json(['foo' => 'bar']);
}
}
```

It's true that showing a deprecation message when the option is not used is a bit annoying and it would be heavy to get rid of it.
Now, a deprecated option is triggered only when it's provided by the user or each time is being called from a lazy evaluation (except for deprecations based on the value, they're triggered only when provided by the user).

This fixes a regression in master, i think after #28809 (or something related)
There's still a "application name" concept out there today, and it's `ConfigDataCollector::getApplicationName()` 🤔
In my case the service resolved to
```php
$e = new \Symfony\Component\HttpKernel\DataCollector\ConfigDataCollector(\basename('/app'));
```
Causing the app name to be, well, `app` (again :P). It was really confusing.
Before:
(the "a" is from "app" here)
After:
or
I think we need to deprecate the argument for real?

[Serializer] Refactor and uniformize the config by introducing a default context

This PR uniformizes how the Serializer's configuration is handled:
* As currently, configuration options can be set using the context (options that weren't configurable using the context have been refactored to leverage it)
* Normalizers and encoders' constructors now accept a "default context"
* All existing global configuration flags (constructor parameters) have been deprecated in favor of this new default context
* the stateless context is always tried first, then is the default context
Some examples:
```php
// Configuring groups globally
// Before: not possible
// After
$normalizer = new ObjectNormalizer(/* deps */, ['groups' => 'the_default_group']);
// Escaping Excel-like formulas in CSV files
// Before
$encoder = new CsvEncoder(',', '"', '\\', '.', true);
// After
$encoder = new CsvEncoder(['csv_escape_formulas' => true]);
$encoder->normalize($data, 'csv', ['csv_escape_formulas' => false]); // Override for this call only
```
Benefits:
* The DX is dramatically improved, configuration is always handled in similar way
* The serializer can be used in fully stateless way
* Every options can be configured globally
* Classes that had constructors with a lot of parameters (like `CsvEncoder`) are now much easier to use
* We'll be able to improve the documentation by adding a dictionary of all available context options for the whole component
* Everything can be configured the same way
TODO in subsequent PRs:
* Add a new option in framework bundle to configure the context globally
* Uniformize the constants name (sometimes the name if `FOO`, sometimes `FOO_KEY`)
* Fix the "bug" regarding the format configuration in `DateTimeNormalizer::denormalize()` (see comments)
* Maybe: move `$defaultContext` as the first parameter (before required services?)
* Make `XmlEncoder` stateless

Right now, as soon as a message is dispatched on a bus, all its handlers are instantiated.
This PR fixes it by leveraging `IteratorAggregate` when possible (implemented by DI's `RewindableGenerator`).

This PR sits on top of #28909 so that only the 2nd commit should be reviewed for now, until I rebase it.
This idea has already been proposed and rejected in #27322.
Yet, now that I've reviewed in depth the component, I politely but strongly suggest to reconsider.
Middleware handlers are the central piece of the routing layer.
When `dispatch()` accepts `object|Envelope`, it's because it sits on the outer boundary of the component. `handle()` on the contrary plugs inside its core routing logic, so that it's very legitimate to require them to deal with `Envelope` objects. Yes, some middleware care only about the message inside. That's fine calling `getMessage()` for them.
Right now, we built a complex magic layer that acts as a band-aid *just* to save this call to `getMessage()`. For middleware that want the envelope, we require an additional interface that magically *changes* the expected argument. That's very fragile design: it breaks the `L` in `SOLID`...
Looking at the diff stat, this is most natural.
