Avoid crash for reset/end/next/prev() on ffi classes (#9711)

This is similar to the fix used in d9651a941915eb5fb5ad557090b65256fd8509b6
for array_walk.
This should make it safer for php-src (and PECLs, long-term) to return
the empty immutable array in `handler->get_properties` to avoid wasting memory.
See https://github.com/php/php-src/issues/9697#issuecomment-1273613175
The only possible internal iterator position for the empty array is at the end
of the empty array (nInternalPointer=0).
The `zend_hash*del*` helpers will always set nInternalPointer to 0 when an
array becomes empty,
regardless of previous insertions/deletions/updates to the array.
