Bug Type:         Bug
Bug description:ReflectionUnionType class does not contain isBuiltin method

Description:
------------
The in php 8 added "ReflectionUnionType" class should extend the
ReflectionType class according to the RFC proposal
(https://wiki.php.net/rfc/union_types_v2#reflection), but the inherited
"isBuiltin" method
(https://www.php.net/manual/de/reflectiontype.isbuiltin.php) does not
exist.

Example script: https://3v4l.org/5BDRn
How it looks like without union type: https://3v4l.org/TGkX2

Test script:
---------------
<?php
class SomeClass
{
    protected string|stdClass $a;
}

$unionType = (new
\ReflectionClass(SomeClass::class))->getProperty('a')->getType();
var_dump($unionType->isBuiltin());

Expected result:
----------------
bool(false)

Actual result:
--------------
Fatal error: Uncaught Error: Call to undefined method
ReflectionUnionType::isBuiltin() in /in/5BDRn:8
Stack trace:
#0 {main}
  thrown in /in/5BDRn on line 8

Process exited with code 255.
