[BUGFIX] Improve performance with symfony/property-info

With the introduction of symfony/property-info, the class
\Symfony\Component\PropertyInfo\Extractor\PhpDocExtractor
has been used to extract property types from the php doc.

Unfortunately said extractor class doesn't cache the so
called context object, which is created repeatedly for
each property of each class.

The context object is used to determine non FQCN's and
its creation comes at very high costs.

To fix this issue, a custom PhpDocExtractor class has
been created which acts just like the original one, but
which caches the context objects.
