We now only preserve the whitespace inside a <t> element inside
the parser. This removes the known n^2 from reattaching whitespace
which should make parsing and appending nodes faster. I also
removed the dead WhitespaceMode code from the parser, and made
the dom-seralizer.sky auto indent the markup so the test output
would be readable.

Instead lets just iterate the list of sheets and ask each one questions. This
shouldn't be much slower since most widgets only have one sheet anyway.
I also moved the media query matching to the sheet collection. We weren't
correctly matching them since we only guarded the feature set, not the
addition to the list of active sheets.

Instead just use textContent() and teach HTMLStyleElement how to atomize
its children. I also added the optimization to Node::textContent so that
Text just returns its value instead of allocating a new buffer which
avoids malloc and copy when getting the textContent of text.

This removes the attributes sky doesn't intend to support. It
removes references to the attrs, but leaves behind a lot of
plumbing that will be cleaned up in the future. This at least
removes the API surface.

This patch is largely just a rename since updateLayoutIgnorePendingStylesheets()
didn't really do anything except call updateLayout() now as nothing was reading
the ignorePendingStyleSheets state, and no callers used the synchronous post
layout task option which was meant for plugins (which Sky doesn't have).
Placeholder styles were related and just add confusion since things pretend to
be display: none while <import>'s are loading. We should expose a real API for
avoiding FOUC instead of pumping frames with display: none elements when
imports are loading.
I had to skip the layout/continuations.sky test since it always crashes now
with an ASSERT failure about a bad cast (filed as bug 446739). The bug already
existed, this patch just makes that one test hit it.

This now means that using a class/id/attribute selector in one scope will
not cause style recalcs in other scopes in the page when something with
that feature changes.
It also removes an iteration over all the scopes that used to collect
features.
I also removed all the extra cases around adding/removing classes since
the general case can handle them.
In addition I removed the check for classStringHasClassName which looked
to see if the string was all whitespace. This check dated way back to
fixing an assert in code we don't even have anymore. Assertion fix aside
all the extra check optimized for was if you wrote class=" " with no
names, which will now cause an extra malloc of the SpaceSplitString::Data.
This seems super rare, it makes more sense to not scan the class string
every time the list of classes changes which is far more common than
setting a string of only whitespace.

Sky doesn't really have many built in elements, we no longer support
<foo is="my-element">. This does mean you can't extend <import>,
<script> or <style>, but we'll figure that out later.

In Sky we can style share if our TreeScopes have the same styles, our :host
styles are the same, and we'd inherit the same styles. This allows a lot of
simplification to the style sharing logic since we don't need to deal with
descendant selectors or tree boundary crossing rules:
- We can remove the logic that was checking that we were distributed
to the same insertion points since there's no ::content selectors.
- We can check the actual inherited values instead of looking at the
parentOrSHadowHostNode(). We used to look at the node in Blink because we
were checking that you'd get the same descendant selectors applied. In Sky
we instead want to make sure you'd inherit the same values. This also
means we don't need the element().parentOrShadowHostElement() != parent case
in the SharedStyleFinder which was trying to deal with descendant selectors
again.
I also removed the checks that were redundant with the checks inside
supportsStyleSharing() which we always check before adding sharing
candidates.
Finally by refactoring the code to make the TreeScope style check work it
exposed that the Document::styleSheets() and TreeScope::styleSheets() APIs
are now dead. A future patch will delete the now dead StyleSheetList class
as well.
This change makes the city-list application share between all the items in
the list, and all of the headers of the same type now share as well.

Particularly, this deletes RenderLayerCompositor. After this,
there's just CompositingState left to remove.
This is all dead code, so there should be no change in behavior.

This is another step towards making attach non-virtual. InsertionPoints are
core to the engine, so it seems fine to bake them directly into recalcStyle.
I did this already to willRecalcStyle.

This hook existed because some elements wanted to run script inside
::insertedInto, but that wasn't a safe time. Now nothing can run script
inside there so we don't need this extra hook.
HTMLStyleElement's usage of this hook is not clear, but it seems like
it might have related to a pre-lazy attach bug.

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.

Fix (most) generated includes to have gen/ in their path.
This makes it easier to tell where files exist on disk.
Unfortunately I had to leave the old include path
in engine/BUILD.gn to support all the v8 includes
which were too many to deal with in this patch.
It's a little nasty to have the raw build directory
in our include path, but it produces nicer paths.

We can simplify the checks given that there's fewer node types now. This does
make the error messages from Range a little worse, but it's weird that Range
is doing its own error checking anyway.
I also took this as an opportunity to add a bunch of DOM tests.
