DevTools: Re-enable a couple of grid-related web tests

We are removing the cssGridFeatures experiment in DevTools (the feature
still exists, it is no longer an experiment).
2 web tests need to be modified to ensure relevant grid-related cases
are taken into account.

These cases were previously removed in this CL:
