[Console] Handle calls to mb_ functions with non string arguments

In PHP8.1, a number of functions who were accepting null arguments will only accept
string ones.
(see https://wiki.php.net/rfc/deprecate_null_to_scalar_internal_arg)

In the polyfill, mb_* functions are already declared with a strict type checking of "string".

Therefore, it is necessary to get rid of the use of non string arguments when calling mb_* functions,
so that it won't break when either using the polyfill,or future php8 versions.

In every call where the argument may not be a string, this commit enforces the string type of the argument (with transtyping)

--- For reviewers
* I generally don't like transtyping, but found it was the more "secure" way (on a non-BC point of view) here.
Specially in Console/Helper/Table.php, where $cell can be an object (there are 2 "$cell instanceof ... tests)
However, where the argument can already be either null or string (and not anything else), there may a beter approach ?

* It's the first time I send a PR on symfony, so don't hesitate pointing me to thinks I've forgotten to done.

[Cache] Fix Redis TLS scheme `rediss` for Redis connection

Like https://github.com/symfony/symfony/pull/35503 on Symfony Messenger, this will enable TLS support for Redis adapter.

The implementation just prefix the host with `tls://` as described here: https://github.com/phpredis/phpredis#connect-open

I don't know how to test it because I guess I need a TLS Redis in `src/Symfony/Component/Cache/Tests/Adapter/RedisAdapterTest.php`.

Switched to non-null defaults in exception constructors

PHP 8.1 will trigger a deprecation warning if we pass `null` as `$message` or `$code` to the constructor of `\Exception`. However, many of our own exception accept `null` for those parameters and even use them as default.

This is unfortunate because code like the following snippet would trigger that deprecation although the code itself is perfectly fine:

```php
throw new NotFoundHttpException();
```

With this PR, I'd like to change our defaults to `''` and `0` while still allowing to pass `null` for BC. In a follow-up PR for the 5.x branch, I'd like to deprecate passing `null`, matching the future behavior of PHP.

This PR also adjust various PHPDoc blocks with inaccurate types.

Inspired by https://github.com/symfony/webpack-encore/pull/900 and by a chat on Slack with @weaverryan

This aims at allowing conditional configuration, which would allow merging config files in one.

Using the PHP-DSL:
```php
$container
    ->when(env: 'prod')
    ->services()
        ->set(Foo::class)
    //...
```

In Yaml:
```yaml
framework:
    secret: '%env(APP_SECRET)%'

when@dev:
    services:
        App\FooForDev: ~

when@test:
    framework:
        test: true
        session:
            storage_factory_id: session.storage.mock_file
```

In XML (omitting namespaces):
```xml
<when env="test">
	<framework test="true">
		<!-- ... -->
	</framework>
</when>

```

A similar syntax is also provided for routes, with support for annotations:
`@Route(env="prod")` defines a route that is enabled only on the "prod" env.

As expained on linked issue, empty forms cannot be removed if they are invalid upon submitting (e.g. transformation failures). Thus, form errors can be displayed properly to the end user.

In the past there was a issue #29736 that the header wasn't processed correctly. To reproduce and prevent this behaviour i extended the tests for this. At the end everything is fine, also in 5.x branch. See bf03d6889d.

Builds on #39851

On PHP8, this PR will allow using an attribute instead of the public static properties for the name and the description.

```php

#[ConsoleCommand(

	hidden: true,

[DependencyInjection] Autoconfigurable attributes

| ------------- | ---
| Branch?       | 5.x
| Bug fix?      | no

Alternative to #39776. Please have a look at that PR as well to see the full discussion.

With this PR, I propose to introduce a way to autoconfigure services by using PHP Attributes. The feature is enabled on all autoconfigured service definitions. The heart of this feature is a new way to register autoconfiguration rules:

```php
$container->registerAttributeForAutoconfiguration(
    MyAttribute::class,
    static function (ChildDefinition $definition, MyAttribute $attribute, \ReflectionClass $reflector): void {
        $definition->addTag('my_tag', ['some_property' => $attribute->someProperty]);
    }
);
```

An example for such an attribute is shipped with this PR with the `EventListener` attribute. This piece of code is a fully functional autoconfigurable event listener:

```php
use Symfony\Component\EventDispatcher\Attribute\EventListener;
use Symfony\Component\HttpKernel\Event\RequestEvent;

#[EventListener]
class MyListener
{
    public function __invoke(RequestEvent $event): void
    {
        // …
    }
}
```

What makes attributes interesting for this kind of configuration is that they can transport meta information that can be evaluated during autoconfiguration. For instance, if we wanted to change the priority of the listener, we can just pass it to the attribute.

```php
#[EventListener(priority: 42)]
```

The attribute itself is a dumb data container and is unaware of the DI component.

This PR provides applications and bundles with the necessary tools to build own attributes and autoconfiguration rules.
