This patch fixes our usage of the pseudo style cache so that we will
use a cached pseudo style when creating pseudo-elements if possible
and so that we cache pseudo styles even if they don't get a renderer.
We also move the logic for having styles with animations or transitions
be non-sharable from RenderStyle::isSharable to the StyleAdjuster, so
that animated pseudo-elements will have their parent's style correctly
marked as non-sharable.

As a result, a pseudo-element without a renderer (e.g. display:none
or content:none) to will correctly return its computed style to
getComputedStyle. This also fixes a regression where the pseudo style
cache can end up very large when its parent style is shared.

This refactors simplifies dependency resolution, and makes it easier to
extend.

Specifically:
* Move file handling into idl_reader
* Move actual definition and interface merging to methods on IdlDefinitions
  and IdlInterface (in idl_definitions)

This also clarifies exactly what's going on specially:
* we tack on some extended attributes to members
* we merge implemented interfaces to the main one

Other changes:
* use next() instead of looping over a one-element list
* remove useless exceptions (specific exception classes are only useful
  if we catch them, otherwise it's no better than a string)

This is to support a separate CL:
Bindings: inherit enums and callbacks from partial interface files.

This patch changes the promise resolution logic of FontFaceSet#load()
to match the spec [1], in the following ways:

1. Rejects the promise with SyntaxError if the font argument fails to
   parse.
2. Otherwise, the promise should be resolved in the same way as
   Promise.all() called with all of the results of FontFace#load() of
   the matching font faces, i.e.
2.1. Resolves the promise with an array of the matching font faces when
     all the fonts are loaded, or
2.2. Rejects the promise with the rejection value of the first failed
     font face.

The new ScriptPromiseResolver Vector overloads need NoInline version of
v8Array, since existing v8Array() uses toV8 inside and hence requires
generated headers (see crbug.com/321569 for details of a similar issue).

This separates the decisions about caching StyleSheetContents for <style> elements
from those related to <link> elements. This makes the code clearer as there are
fewer conditions that could cause uncacheability (for example, the StyleSheetContents
for <style> elements could never be for an @import rule).

And since the <style> cache is per-StyleEngine (and thus per-Document), the
<style> case can now safely cache stylesheets that include @media rules.
This speeds up the included performance test from ~90ms on my Z620 to ~50ms,
and improves the biggest block of chromestatus.com load performance by ~20%.

This patch also cleans up StyleSheetContents a bit, collapsing the maybeCacheable()
method into isCacheable() and making appropriate accessors const.

Instead of keeping a separate hash map we should just store this
information in the ElementRareData. This simplifies the implementation and
in practice will likely reduce memory usage since almost all custom elements
we've seen so far touch something that ends up making them use rare data like
childNodes, attributes, tabIndex, classList or dataset.

This patch fixes a bug where resources in element.animate() calls were
not being fetched. This resulted in StylePendingImages leaking out of
the style resolving stage and into rendering which causes a crash.

This patch fixes the bug by ensuring StylePendingImages introduced in
applyAnimatedProperties() will be resolved as non-pending StyleImages
through an additional call to loadPendingResources().
This patch also modifies AnimatableImage to be a wrapper of CSSValues
instead of StyleImages in order to follow the same resource caching
logic as typical CSS image values.
This patch also updates EffectInput::convert() to pass the document's
StyleSheetContents to MutableStylePropertySet::setProperty() so that
relative URLs are correctly resolved to absolute URLs.

This is a reland of https://codereview.chromium.org/196573030/ with

This further simplifies EventTarget bindings generation.

The goal (for now) is to only have a special case for the
{{hidden_dependency_action}}; everything else should be pretty easy
to eliminate (except maybe the ListenerFindOnly case).

The main change in this CL is making the argument handling regular.
(Also correctly handles EventListener as a callback interface.)

This also breaks up the big custom generation into smaller pieces,
so each piece can be eliminated separately.

RenderBlock::percentHeightDescendants() is used to schedule layout of
descencents of a block when the logical height of the block changes.
It should contain descendants having percent height whose real height
calculation depends on the height of the block.

Previously
- the set doesn't contain direct children;
- skipped containing blocks for percent height calculation unnecessarily
  have the set.

Let the set contain all necessary objects. This doesn't fix any
functional breakage for now, but later layout optimization may depend

Since r168759 we use bilinear filtering for animated images. There
are complaints about the drop in image quality. However we don't want to
spend a lot of CPU cycles doing high quality animations for upscaling.
This change is a compromise for animated images: we do a cheaper
mipmapping for downscaling and bilinear for upscaling. There is a
noticable quality improvement.

This change implements InterpolationMedium for GraphicsContext. It used
to be equivalent to InterpolationLow and is now a higher quality option.
All GraphicsContext::drawSomething() methods have |useLowQualityScale|
removed. This gives a much cleaner code.

I also discovered/fixed a couple small issues with interpolation levels:
* It is apparent now that InterpolationDefault means InterpolationHigh
  on desktop and InterpolationLow on Android.
* Default for canvas elements used to InterpolationMedium but it
  really meant InterpolationLow.
* There is a bug for rendering images in canvas that InterpolationNone
  should be used but it has been InterpolationLow all along. I didn't
  fix in this change but added a FIXME.

The new interpolation level does not affect non-animated images. There
is no need to rebaseline any pixel test. I added a test GIF file that
loops two identical frames. This is used to test the image quality.
