[php-src] Issue #21420: Error in the repeat 2 logic: php_request_shutdown is not called the second time.

### Description

There is a bug in the repeat 2 logic caused by an incorrect goto inside a zend_try block. This bug does not manifest in most cases, but I encountered it in tests with the async core.

```
zend_try {                          // 619 — SETJMP + EG(bailout) = &__bailout
      // ...
  do_repeat:                          // 871 — goto jumps HERE
      // ...
      php_execute_script();           // has its own zend_try inside
      // ...
  } zend_end_try();                   // 1149 — EG(bailout) = __orig_bailout
  out:
      php_request_shutdown();         // 1156
      goto do_repeat;                 // 1171 — jumps to 871
```

**After Round 1:**
  1. zend_end_try() (1149) — restores EG(bailout) = __orig_bailout
  2. php_request_shutdown() — OK
  3. goto do_repeat — jumps to 871

**Round 2 — the problem:**
  - SETJMP at line 619 is NOT called again
  - EG(bailout) points to __orig_bailout (the outer handler), not &__bailout
  - When php_execute_script does its own zend_try, it saves __orig_bailout as its parent
  - When zend_bailout() at scheduler.c:1216 fires → it jumps past do_cli() entirely → php_request_shutdown() is NOT called on Round 2!

The flow goes straight to main() → php_module_shutdown() → executor_globals_dtor() → ...

This is the root cause! The bug is in php_cli.c itself — goto do_repeat jumps into the middle of a zend_try block without reinitializing SETJMP.
That is, when the CLI runs in repeat mode twice, it is not cleaned up correctly the second time. The request shutdown is not called.
