Highwater condition with unjoined maps skips unprocessed and NEEDS_UPDATE rows

The patch has this code:

         if ($this->mapJoinable() && $high_water !== NULL) {
           $conditions->condition($high_water_field, $high_water, '>');
           $condition_added = TRUE;
         }

But then, inside mapJoinable we have this:

    if ($this->batchSize > 0) {
      return FALSE;
    }

So, if I understand correctly, with the solution suggested on the patch, there is no way to use both high water marks and batch size. If you set a batch size, then the water mark conditions will not be executed.

Patch #58 didn't work for D10.3.

Added new patch for D10.3.
