The code to make them dynamically update was already removed when
Document::inheritHtmlAndBodyElementStyles was removed. We might want
to add them back later, but probably in a different way, so lets
remove the code for now to make refactoring the style system easier.

We can just set the style as unique from inside the SelectorChecker
instead. That's not ideal either, but it's simpler, and we'll eventually
use a hashing function to instead make elements with attribute selectors
that have the same values share their style instead of disabling
sharing.

We can also remove all single document checks since in Sky we
don't have the cross document cache so all sheets are always
connected to a single document.
I also did some minor code simplification and removed an
OILPAN ifdef.

We don't need this since we don't expose the list of sheets from Document
or ShadowRoot in Sky. After removing this code I also simplified the
system and deleted StyleSheetCandidate and DocumentStyleSheetCollector
which don't really do anything anymore.
Even if we do want to add back a list of sheets later it won't need code
because we don't have a concept of a remote sheet like <link rel> did,
and we don't have to deal with non-CSS sheets.

This existed apparently to track if a CSS file had at least
a valid CSS rule at the start to attempt to mitigate cross
origin CSS attacks where a file with an invalid mime was
sniffed as CSS and then we skipped the first part which
was not valid, but then interpreted the latter half of
the file as valid CSS.
In Sky all content is same origin, so we don't need this
mitigation.

This was used to skip caching sheets across documents that had failed
resource loads so that when you loaded a new tab with the same resource
we'd attempt to load it again.
The cross document cache (which was only used by <link>) doesn't exist
in Sky, and neither does CSSStyleSheetResource which used it, so we can
remove all this code.

This optimization doesn't make sense, all it does is avoid adding
the ScopedStyleResolver for the ShadowRoot when looking for host
styles, but having that extra resolver shouldn't be slow, and in
sky it's very rare to have a ShadowRoot without styles unlike
on the web where <input> is very common and gets its style from
the UA instead of from a <style> like a normal component.

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.

Instead of trying to match the actual attribute rules, lets just look
at the HashSet of attribute names. This is faster, though possibly less
optimal if you use compound rules like .foo[attr]. That's rare though,
and removing this extra RuleSet will allow simplifying SelectorChecker
since hasAnyMatchingRules required a special mode where it tried to
match selectors but ignored if the scope could really match. This paves
the way to moving the RuleFeatureSet to be per-TreeScope instead of
per-Document.
I also made the API of classNamesAffectedByRules match the newly added
attributesAffectedByRules to make SharedStyleFinder consistent.

This patch remove the Web Animations & CSS Animation runtime flags (and enables both). Removes prefixed Aninamations & Transitions and adds some basic tests & test support API.

The parser will never insert more than one child into a <style>, so we don't
need explicit logic to batch up parsing. Once I removed that it exposed that
all the line number and parser created logic is from error reporting in the
parser that's been dead in Blink for over a year.
By doing this simplification I was able to remove the finishParsingChildren()
callback entirely.

The StyleRule classes supported copy() operations and mutable
property sets so that we could do copy-on-write and mutate them
using the CSSOM. Sky doesn't have a CSSOM like this though,
so we can remove all this code and make the StyleRule classes
effectively immutable after construction (the parser does mutate some
rules though).
I also removed some other dead code in the StyleRule hierarchy,
like some left over mutation methods that the CSSOM used to use.

We should come up with a better way to implement this feature for the
inspector, the current implementation uses CSSOM wrappers and is n^2
over the number of rules in the page.

In preparation of simplifying how we collect and process sheets now
that we don't support descendant, sibling and tree boundary crossing
rules we should switch to always going down the Reconstruct path.
This might be somewhat slower to start, but because our rules are so
much simpler we should be able to rebuild the StyleEngine to do
something simpler and faster.

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 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.

-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.
