Use symfony decorators

[goetas]

Use symfony decorators to decorate metadata drivers and object constructors.

This simplifies a lot the code and makes possible a better decoration process. the previous implementation was self-implementing the decoration process

This has some BC change because aliasing the service to replace the constructor is overridden by decoration now.

I was creating a alias my self of the jms_serializer.object_constructor to my service and now the decorator override it.

I am trying to find a way to be compatible with <= 3.6.0 and >= 3.7.0 at the same time.

I endup doing a compiler pass:

`class JmsDoctrineObjectConstructionCompilerPass implements CompilerPassInterface
{
public function process(ContainerBuilder $container)
{
if(null === $container->getDefinition('jms_serializer.doctrine_object_constructor')->getDecoratedService()) {
return;
}

    $container->removeDefinition('jms_serializer.object_constructor');
    $container->setAlias('jms_serializer.doctrine_object_constructor', DoctrineObjectConstructor::class);
    $container->setAlias('jms_serializer.object_constructor', 'jms_serializer.doctrine_object_constructor');
}

}`
