[css-grid] Stretching auto tracks should be done as part of the track sizing algorithm

[Manuel Rego Casasnovas]

CSS WG has agreed to modify the track sizing algorithm to include a new step: https://drafts.csswg.org/css-grid/#algo-stretch

We used to do the stretch of the "auto" tracks at the end of the track sizing algorithm, however the change integrates this into the algorithm itself as the last step.

See: https://github.com/w3c/csswg-drafts/issues/1150
