Emilio Cobos Álvarez f85c48f96d Bug 1525107 - Implement <meta name=color-scheme>. r=dholbert
There are still tests failing because
https://bugzilla.mozilla.org/show_bug.cgi?id=1736034 hasn't been synced
yet.

Once that lands, they will still fail because we don't change
Canvas/CanvasText based on color-scheme, but that I'm attaching
patches for after this one.
