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.
Instead of applying animations and transitions to styled elements,
include them in the cascade. This allows them to interact properly with
things like font-size and !important rules.
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`.

This should help out quite a bit with uBO, which has lots of very
general attribute selectors. We invalidate per attribute name rather
than using a SelectorMap, which prevents matching for attribute
selectors that can't have changed.
The idea is that this should be generally cheaper, though there are
cases where this would be a slight pesimization. For example, if there's
an attribute selector like:
my-specific-element[my-attribute] { /* ... */ }
And you change `my-attribute` in an element that isn't a
`my-specific-element`, before that the SelectorMap would've prevented us
from selector-matching completely. Now we'd still run selector-matching
for that (though the matching would be pretty cheap).
However I think this should speed up things generally, let's see what
the perf tests think before landing this though.

This addresses a minor regression in bloom-matching.html. The common
case here is that there's no selector to the right of the
pseudo-element, so keep that path inline, while keeping all other checks
out of line.
