-Make display:flex, flex-direction: column, flex-shrink: 1 the default.
-Simplify StyleAdjuster::adjustStyleForAlignment to remove special cases we
won't need as we make flex the default and remove absolute positioning.
-Fix a bug this exposed in column flexboxes where we'd apply the wrong edge
of border/padding/margin.
-For now leave the default of align-items:stretch. The main change here is
that iframe/img will do width:auto the same as blocks (i.e. the width of
the parent). I think this is a good change, but we'll have to see how it feels
in practice.

On the web, if you set position:absolute, but not
top/right/bottom/left, then the absolute goes where it
would have gone if it wasn't positioned. The use-cases for
this are slim and it introduces a lot of complexity to the
engine.
Also changes behavior in the presence of direction:rtl.
On the web, direction:rtl and top/left:auto would
sometimes set right:0. Instead we always position at
0,0 if the opposing values are auto.
This removes the code for this positioning and allows
simplifying a bunch of dirty bit handling code since
we don't need to setNeedsLayout if lines move around
or wrap differently.
The test cases did change their output, but the new
positioning all looks correct to me.

The only bit that was still used was the
containingBlockLogicalWidthChanged check in
RenderBlock::widthAvailableToChildrenHasChanged.

is the patch that added that code. I added a
test to confirm we still pass the test case
that code was added for.

This is the first step of getting rid of RenderLayer.
Instead of walking the RenderLayer tree, wall the RenderObject
tree and add any layers encountered to a vector to paint later.
This patch just consolidates and move the code from RenderLayer
to RenderBox and then changes the children painting to
iterate over the vector. Therefore we walk the RenderObject tree.
We still call out to RenderLayer in a bunch of places.
A followup patch will get rid of those.

We've simplified RenderBlock::layout to the point where we
no longer need it or layoutBlock. The RenderBlock subclasses
can just override layout the way every other renderer does.

This is all wasted effort in sky since we invalidate
the whole viewport on every frame. We'll probably eventually
add back in some invalidation, but it likely won't
be rect-based.

This caused us to lose our gn check certification. :(
Turns out gn check was just ignoring all the header
paths it didn't understand and so gn check passing
for sky wasn't meaning much. I tried to straighten
out some of the mess in this CL, but its going to take
several more rounds of massaging before gn check
passes again. On the bright side (almost) all of
our headers are absolute now. Turns out my script
(attached to the bug) didn't notice ../ includes
but I'll fix that in the next patch.

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.
