[GridNG] Add extra margins to a subgridded item's contribution size

1. Introducing fields in NGGridLayoutTrackCollection to accumulate the
   start/end extra margin from subgrids, which will be used to compute
   the respective extra margin to be added to subgridded items.

   Also adding methods to compute the start/end extra margins to be
   applied to specific track spans within a track collection.

2. Adding the start/end extra margin to a subgridded item's contribution
   size. This extra margin will accommodate any ancestor subgrid's
   margin, border, scrollbar, padding, and gutter size.

3. Correcting an invalid definition for grid-column in the WPT test
   auto-track-sizing-001.html and its respective reference file.
