[css-grid] Remove compilation flag ENABLE_CSS_GRID_LAYOUT

[Manuel Rego Casasnovas]

Now that CSS Grid Layout is enabled by default (r211415) and Safari 10.1 is shipping it [1],
it seems we might not need the compilation flag anymore.

Nice work. I guess that having a runtime preference won't make much sense either, but we could remove it in a follow up patch.

I'm giving r+ but wait some time for an Apple review (although I guess they'll be fine with the change as Safari is shipping it).

Perhaps you could put these three in a single line now

Thanks for the review.

Now let's wait for some feedback from Apple reviewers.

Patch is ready for landing and waiting for Apple's feedback.

If nobody complains during this week, I think it's safe we land it.
