WIP php8-attributes

[Selion05]

@ichiriac @czosel

The Current implementation can handle code like <?php #[Attribute("aoeu",'stnh'),Attribute(),SUP] class Whatever {} as well as named properties <?php #[Attribute(someProp: 'stnh')] class Whatever {}. But it feels like i duplicated logic. Any feedback?

The tokens are equal to token_get_all in php

todo

• handle \n in attributes
• tests
