Fix incorrect zval type_flags in preg_replace_callback_array() for im…
…mutable arrays The ZVAL_ARR macro always set the zval type_info to IS_ARRAY_EX, even if the hash table is immutable. Since in preg_replace_callback_array() we can return the passed array directly, and that passed array can be immutable, we need to reset the type_flags to keep the VM from performing ref-counting on the array. Fixes GH-10968 Closes GH-10970
