Margin collapsing is a document-oriented feature. For applications
it just causes confusion and slowness.
margins.sky has failure output because offsetTop is returning the
wrong values. That's not new with this patch though. When I look
at it visually in skydb, everything seems to be in the right place.

The two are unrelated, but it was easier to just grep for grid
and remove them all. Aside from the media query change, there
isn't any change in behavior since grid was behind a flag.

This just removes a random subset of vertical writing mode bits
that I grepped for. There's a ton more to do, but it seems best to
do it in chunks.
The key things for understanding this patch, isWritingModeRoot is
always false and isHorizontalWritingMode is always true. Also,
we're never flipped* modes of any kind, so we can undo any flipping.
