Generate __toString() magic method with all fields #6783

• [PHP] Generate __toString in a Plain Object class #6783
• Add/Fix unit tests

Example:

class Person {
    public string $name;
    private int $age;
    protected string $phoneNumber;
    private string $emailAddress;
}

Result:

class Person {
    public string $name;
    private int $age;
    protected string $phoneNumber;
    private string $emailAddress;
    public function __toString(): string {
        return "Person[name=" . $this->name
                . ", age=" . $this->age
                . ", phoneNumber=" . $this->phoneNumber
                . ", emailAddress=" . $this->emailAddress
                . "]";
    }
}
