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.

These appear to have been for ensuring that you
only paint elements in a given subtree. It's not clear
to me exactly how you get to painting an element that
is not rooted at the RenderLayer you started with.
I think it's just not possible in Sky anymore.
This code was added in 2004 for drag images, which
we no longer support.

Mostly just mechanical changes. The one surprising bit
is that RenderLayer no longer needs to explictly paint
outlines. I tested manually that before this patch,
the paintOutline call in RenderLayer was needed for
outlines on positioned elements and that after this
patch it's not.

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.

Jagged edge outlines are more complexity than is justified
for the use-cases. We should enable to use-cases like this,
but with a lower-level line-box + custom painting API.
Removes the paintOutline method on RenderInline. Also removed
a number of dead methods that call absoluteRects so we can delete
that method and related code.

First step in getting rid of paint phases. Verified that
deleting this phase entirely would cause flights-app-pixel.sky
to fail and that it still passes in this patch, which just does
the background painting as part of the foreground phase.

This is an optimization to avoid painting backgrounds
that are obscured. It's a lot of complexity that it's
not clear we'll need given that we're using a GL backend.
Also, we can add it back in more easily/efficiently in the future
once we have a display list architecture.
This also means we can remove the needsPaintInvalidation
dirty bit and some opacity information on filters.

There is a slight change in behavior in FrameSelection::revealSelection.
If you have a non-collapsed selection, then we'll center the start
of the selection instead of the whole selection in some cases. There's
a ton of callers of this code, so it's hard to be sure if any of this
actually changes behavior for sky. In manual testing, I couldn't find
any scenarios where there was a difference. Almost universally,
when we call revealSelection, we have a CaretSelection. The only
case I could think of where we have a RangeSelection is when
modifying an off-screen selection (e.g. shift+right), but in that case
we pass the RevealExtent option, so this patch doesn't change behavior
there.
Removing that caller makes all the rest of this rect computing
code into dead code.

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.

The only place it's used now is making it so that
anonymous flex items don't do ellipsizing the same
way anonymous items inside a block would. This
is something we don't need, especially now that
we only have anonymous paragraphs around text nodes.
It's not clear to me if we want this looking at the
parent behavior at all, but that's something that
can be fixed in a followup.
Also delete some dead anonymous block functions.

-Add RenderParagraph and display:paragraph. This is the only
render type that's allowed to contain inlines or text.
-If you put text nodes directly in a non-paragraph, wrap them
in an anonymous paragraph. This may not be the place we want
to end up, but it's a good stopgap to make it so we don't
crash in this case.
-Make StyleAdjuster force that non-paragraph blocks only contain
RenderBlock subclasses and that paragraphs and inlines only contain
inlines.
-Considerably simplify addChildIgnoringAnonymousColumnBlocks
now that we only create anonymous blocks for the case of
text nodes in non-paragraphs. Also get rid of the behavior
where we try to group multiple nodes into a single
anonymous block.

We never paint scroll corners. The only thing we need them
for is so that the vertical and horizontal scrollbars don't
overlap each other. So, that's the only place left that
still computes a scroll corner rect.
We don't support resizers. Remove the code for them as well
as the CSS resize property.

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.
