Store abspos boxes in a RefCell too
We want to mutate them when lazily computing their content sizes, but they
are behind an Arc for the hoisting infra, so it also needs its own layer
of inner mutability.
Add UI for bypassing SSL handshake failures
There are several parts to these changes:
1. resurrecting the network error classification code to distinguish between SSL failures and other network errors
1. adding an SSL verification callback to support verifying certs against a list that can change at runtime, rather than just at program initialization
1. exposing a privileged chrome://allowcert URI which accepts the PEM cert contents along with a secret token
1. extracting the PEM cert contents out of the network layer when a handshake failure occurs, and getting them into the HTML that is parsed when an SSL failure occurs
1. adding a button in the handshake failure page that performs an XHR to chrome://allowcert with knowledge of the secret token and the PEM cert contents, before reloading the original URL that failed
The presence of the secret token means that while the chrome://allowcert URL is currently visible to web content, they cannot make use of it to inject arbitrary certs into the verification process.

Update webrender
These changes reflect changes in webrender's API that make RenderApiSender and RenderApi objects more challenging to share. This PR moves us to a model where:
* the compositor owns the main RenderApi object
* other threads that need to create transactions or manipulate fonts proxy those operations to the compositor (script/layout use IPC, while other threads use non-IPC channels)
* the webgl thread owns its own independent RenderApi
Don't create empty stacking contexts in display lists
A recent change to euclid exposed that our display lists can contain Rects that contain NaN values. These NaNs originate from creating stacking contexts with transforms that scale the horizontal or vertical dimensions to 0. WebRender isn't prepared to handle these, so we need to not produce these empty stacking contexts when building the display list.

We want to mutate them when lazily computing their content sizes, but they
are behind an Arc for the hoisting infra, so it also needs its own layer
of inner mutability.
We want to compute content sizes on demand rather than eagerly so we will
need to mutate the independent formatting contexts that own the content sizes.
layout_2020: Tag fragments with their pseudo content type
This will allow us to answer queries and properly handle animations in
the future for fragments generated for pseudo content.

This begins to address #26625 by properly applying CSS variables during
keyframe computation and no longer using `apply_declarations`. Instead,
walk the declarations, combining them into IntermediateComputedKeyframe,
maintaining declarations that modify CSS custom properties. Then compute
a set of AnimationValues for each keyframe and use those to produce
interpolated animation values.
Instead of recalculating the animation style every tick of an animation,
cache the computed values when animations change. In addition to being
more efficient, this will allow us to return animation rules as property
declarations because we don't need to consult the final style to produce
them.
Reduce scope of generic code in script
Combined, these changes account for almost 100k lines of generated code in a debug build for the script crate.

Remove support for energy and heartbeats profiling
Both are disabled by default (energy at compile-time, heartbeats with a run-time option). Neither is tested of CI. Neither has been used in a long time. They might have Undefined Behavior: https://github.com/servo/servo/issues/26550#issuecomment-634238098. They each depend on a mostly-unmaintained C library. The thread-safety expectation of those libraries are unknown.

Prefix `on` for function name of inline events
While checking what needs to be done for the spec-update, I've noticed the logic of checking `is window-reflecting element (e.g. body and frameset)` is already handled by the `is` casting function.
However, we still failed to pass the tests because we're missing `on` prefix for inline functions.
I'm not sure if this patch is good enough (or maybe at least I need to add a comment for why adding `on` prefix?).
Besides, I checked [how Gecko handles](https://searchfox.org/mozilla-central/rev/8bc4e35c9bb47c1fe3131e6155d9f482e1efef9a/dom/events/EventListenerManager.cpp#1012-1022) and looks like they also just pass the atom directly.
But, the [generated atom](https://searchfox.org/mozilla-central/source/__GENERATED__/xpcom/ds/nsGkAtomList.h#775) is prefixed with `on` which is correct to just pass it into the `CompileFunction`.
