Left :

• Lexer deprecation on many jobs Replace object-like array with class doctrine/lexer#79
• In ORM 3.0, the AttributeDriver will report fields for the classes where they are declared. This may uncover invalid mapping configurations. To opt into the new mode also with the AnnotationDriver today, set the "reportFieldsWhereDeclared" constructor parameter to true. (AnnotationDriver.php:80 called by AppKernelTestDebugContainer.php:4566, Make Annotations/Attribute mapping drivers report fields for the classes where they are declared doctrine/orm#10455, package doctrine/orm)
• PHP 8.1 dev fails on deprecation, with a lot of annotation things. I'm not sure how to keep a layer for annotation but use attributes on this branch.

friendly ping @soyuka for review and the two things left, after them all PHPUNIT should be green
