Adds support for modern PHP syntax analysis

Improves the analysis of PHP classes by adding support for modern syntax features (PHP 8.1+), including enums, readonly properties, attributes and interface analysis within classes.

The update ensures accurate identification of class dependencies and correct flagging of abstract/interface status when modern syntax is used.
