This PR adds custom tags support to the Yaml component.
Symfony tags (`!!binary`, `!str`, etc.) are still managed in the parser to have a lighter diff but we'll be able to convert them later if we want to.
The primary addition of this PR is the `TagInterface`:
```php
interface TagInterface
{
public function construct(mixed $value): mixed;
}
```
It can be used to register custom tags. An example that could be used to convert [the syntax `=iterator`](https://github.com/symfony/symfony/pull/20907#issuecomment-270728216) to a tag:
```php
final class IteratorTag implements TagInterface
{
public function construct(mixed $value): mixed
{
return new IteratorArgument($value);
}
}
$parser = new Parser(['iterator' => new IteratorTag()]);
```
If you think this is too complex, @nicolas-grekas [proposed an alternative](https://github.com/symfony/symfony/issues/21185#issuecomment-271074840) to my proposal externalizing this support by introducing a new class `TaggedValue`.

README
What is Symfony?
Symfony is a PHP full-stack web framework. It is written with speed and flexibility in mind. It allows developers to build better and easy to maintain websites with PHP.
Symfony can be used to develop all kind of websites, from your personal blog to high traffic ones like Dailymotion or Yahoo! Answers.
Installation
The best way to install Symfony is to use the official Symfony Installer. It allows you to start a new project based on the version you want.
Documentation
The "Quick Tour" tutorial gives you a first feeling of the framework. If, like us, you think that Symfony can help speed up your development and take the quality of your work to the next level, read the official Symfony documentation.
