[PHP] Statement after never function call might be display warning message

### Apache NetBeans version

Apache NetBeans 16

### What happened

```never``` type was introduced in php 8.1 ([never](https://wiki.php.net/rfc/noreturn_type)).
Some statement after never function call might be not executed, and should display warning message just to inform user.

### How to reproduce

```php
fetchDb() ?? $gateway->thrower();
echo "after"; // this statement might be executed and SHOULD NOT display warning message.
```

### Did this work correctly in an earlier version?

No / Don't know

### Operating System

Windows 10

### JDK

Java: 14.0.1; Java HotSpot(TM) 64-Bit Server VM 14.0.1+7 Runtime: Java(TM) SE Runtime Environment 14.0.1+7

### Apache NetBeans packaging

Apache NetBeans provided installer

### Anything else

_No response_

### Are you willing to submit a pull request?

No

### Code of Conduct

Yes

No source file or test is identified in the report; start by reproducing both PHP examples in NetBeans 16 with PHP 8.1 and locate the existing unreachable-code warning path for never-returning calls. Done means a warning appears for the statement after redirect(), while the null-coalescing example does not produce that warning, with regression coverage for both cases.
