php_array_merge_recursive() recurses once per nesting level with no stack check, so
array_merge_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.
Fixes #23089.
