EnumDeclaration does not support classInterfaceClause

[zobo]

Docs and various sources say enums can implement interfaces:
https://wiki.php.net/rfc/enumerations
https://www.php.net/manual/en/language.enumerations.methods.php

It can already parse implements X, Y for enums

EnumDeclaration has enumInterfaceClause instead, with the same implementsKeyword/interfaceNameList properties as classInterfaceClause
