Reverting sharing of descriptor arrays:

Reverting sharing of descriptor arrays:

- Sharing of descriptor arrays.
- Ensure correct enumeration indices in the dict.
- Clear the EnumLength fields of maps that lose their enumeration cache.
- Directly set the value in the descriptors pointer to avoid checks.
- CNLT with descriptors but no valid enum fields has to clear the
  EnumCache.
- Only count the descriptor array if it's owned by the map.
- Restore the descriptor array before returning allocation failure.
