php_array_walk() recurses once per nesting level with no stack check, so array_walk_recursive() on a deeply nested array exhausts the native stack and the process dies with a segfault.

This adds the same stack limit check ext/standard already uses in var.c and http.c, so the call throws an Error instead of crashing. The existing GC_IS_RECURSIVE guard only covers self-referential arrays, not plain deep nesting.

Fixes #23111.
