These are values for text-align that align blocks in addition to
inline content. You can get the same centering affect with margin:auto.
If we want this functionality, we should implement it with the
same alignment APIs that we use for flexbox.
Delete unused methods/arguments from RenderBlockFlow.
No change in behavior. Just deleting dead code.

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.
