StackingContexts that should be painted on top of StackingContexts that
are already layerized should automatically get their own layer. This
will ensure proper painting order.
layout: Centralize the logic that determines whether fragments get layers in the fragment.
…so that it can be activated when we're forcing
the creation of extra layers due to positioned descendants that
themselves have layers.
The newly failing tests were tests that accidentally passed due to
incorrect stacking order.
Closes#7281.

* Don't display unselected `<option>` elements inside `<select>`
dropdowns.
* Use CSS triangles to give `<select>` dropdowns a down arrow in order
to make them look as intended.
* Use borders instead of `( )` and `[ ]` for radio buttons and check
boxes, respectively.
Improves facebook.com and IMDB.
Improves the Google SERPs.
We mark `html/rendering/replaced-elements/images/space.html` as failing.
This test tested whether `<img hspace>` and inline margins do the same
thing. Since this was trivially the case before (since we implemented
neither) and now is not, this test now fails.
* Simpler image cache API for clients to use.
* Significantly fewer threads.
* One thread for image cache task (multiplexes commands, decoder threads and async resource requests).
* 4 threads for decoder worker tasks.
* Removed ReflowEvent hacks in script and layout tasks.
* Image elements pass a Trusted<T> to image cache, which is used to dirty nodes via script task. Previous use of Untrusted addresses was unsafe.
* Image requests such as background-image on layout / paint threads trigger repaint only rather than full reflow.
* Add reflow batching for when multiple images load quickly.
* Reduces the number of paints loading wikipedia from ~95 to ~35.
* Reasonably simple to add proper prefetch support in a follow up PR.
* Async loaded images always construct Image fragments now, instead of generic.
* Image fragments support the image not being present.
* Simpler implementation of synchronous image loading for reftests.
* Removed image holder.
* image.onload support.
* image NaturalWidth and NaturalHeight support.
* Updated WPT expectations.
