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.

I also fixed several errors in our BUILD.gn files
including bad script dependencies found by
missing_from_gn and gn check.
Still need to figure out how best to handle
:libraries deps being private to :core, etc.
