[5.2] Support column aliases in chunkById

[mzur]

This is a follow-up on #14499 where chunkById should be fixed to support more complex queries. The following query currently does not work:

// both the annotations and images tables have an id column
DB::table('annotations')
   ->join('images', 'annotations.image_id', '=', 'images.id')
   ->where(/* something with images */)
   ->chunkById(500, $handleChunk, 'annotations.id');

With this PR it can be done like this:

DB::table('annotations')
   ->join('images', 'annotations.image_id', '=', 'images.id')
   ->where(/* something with images */)
   ->select('annotations.id as annotations_id', /* ... */)
   ->chunkById(500, $handleChunk, 'annotations.id', 'annotations_id');
