/**
* Creates an object and sets its properties without calling its constructor nor any other methods.
*
* For example:
*
* // creates an empty instance of Foo
* Instantiator::instantiate(Foo::class);
*
* // creates a Foo instance and sets one of its properties
* Instantiator::instantiate(Foo::class, ['propertyName' => $propertyValue]);
*
* // creates a Foo instance and sets a private property defined on its parent Bar class
* Instantiator::instantiate(Foo::class, [], [
* Bar::class => ['privateBarProperty' => $propertyValue],
* ]);
*
* Instances of ArrayObject, ArrayIterator and SplObjectHash can be created
* by using the special "\0" property name to define their internal value:
*
* // creates an SplObjectHash where $info1 is attached to $obj1, etc.
* Instantiator::instantiate(SplObjectStorage::class, ["\0" => [$obj1, $info1, $obj2, $info2...]]);
*
* // creates an ArrayObject populated with $inputArray
* Instantiator::instantiate(ArrayObject::class, ["\0" => [$inputArray]]);
*
* @param string $class The class of the instance to create
* @param array $properties The properties to set on the instance
* @param array $privateProperties The private properties to set on the instance,
* keyed by their declaring class
*
* @throws ExceptionInterface When the instance cannot be created
