Adopt PHPCS config from Drupal core that is missing in Coder

Missing EmptyPHPStatement found, added in https://github.com/pfrenssen/coder/pull/250

Adapted the PropertyDeclaration sniff and directly use it from PSR-2 https://github.com/pfrenssen/coder/pull/251 (sorry did not put the correct issue number in the git log).

Core issue already exists: 📌 Keep all sniffs in phpcs.xml.dist in sync with the list got from the locked version of coder Needs work .

Otherwise I'm done here, we are in sync again.

Automatically closed - issue fixed for 2 weeks with no activity.
