Add PHP 8.0 support, remove Annotation support

[Slamdunk]

Take place over https://github.com/doctrine/DoctrineORMModule/pull/661

Of course this is a BC Break for dropping the Annotation support, but that's the only way we can release PHP 8.0 support now without adding more code.

I have projects using DoctrineORMModule\Form\Annotation that I would like to prepare for PHP7.4 (and PHP8.0 as the next step) upgrade (I require php ^7.4 in my composer.json). When I run composer install, I realized that I have no AnnotationBuilder anymore. Do I basically have to remove AnnotationBuilder from my existing projects and change it with, let's say, Laminas\Form? I loved Doctrine AnnotationBuilder, sorry to lose it. Thank you.

@smozgur what version of this repository are you using? That would dictate whether there is an annotation builder.

Thanks for the reply, @TomHAnderson .

I just realized that I am using 4.0. I rebuilt this project from scratch as it would be a chance for a clean-up as well, so it should have installed this version since I have php ^7.4 in composer. I see that the version 1.1 is installed in the original project. Is it going to work without problems when I downgrade the that version even in PHP8?

Old composer.json:

        "php": "7.3",
        "doctrine/orm": "^2.5",
        "doctrine/doctrine-orm-module": "^1.1",

New composer.json:

        "php": "^7.4",
        "doctrine/orm": "^2.8",
        "doctrine/doctrine-orm-module": "^4.0",

OK, so if you want annotations why are you using v4.0 when that is the version which removes the annotations? Use the readme docs on versioning and stick to the 3.x series.

[smozgur]

Yes, I would do that.

Thank you for your help.
