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

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`.

build(deps): bump proc-macro2 from 0.4.26 to 0.4.30
Bumps [proc-macro2](https://github.com/alexcrichton/proc-macro2) from 0.4.26 to 0.4.30.
<details>
<summary>Release notes</summary>
<p><em>Sourced from <a href="https://github.com/alexcrichton/proc-macro2/releases">proc-macro2's releases</a>.</em></p>
<blockquote>
<h2>0.4.30</h2>
<ul>
<li>Implement Clone for TokenStream's IntoIter (<a href="https://github-redirect.dependabot.com/alexcrichton/proc-macro2/issues/177">#177</a>, thanks <a href="https://github.com/ivanbakel">@ivanbakel</a>)</li>
</ul>
<h2>0.4.29</h2>
<ul>
<li>Support compiling with <code>RUSTFLAGS='-Z allow-features='</code> on a nightly compiler (<a href="https://github-redirect.dependabot.com/alexcrichton/proc-macro2/issues/176">#176</a>, thanks <a href="https://github.com/Nemo157">@Nemo157</a>)</li>
</ul>
<h2>0.4.28</h2>
<ul>
<li>Avoid needlessly escaping <code>'</code> inside a string literal or <code>"</code> inside a character literal (<a href="https://github-redirect.dependabot.com/alexcrichton/proc-macro2/issues/60">#60</a>)</li>
<li>Add impls of Copy, Clone, Debug, PartialEq, Eq for proc_macro2::LineColumn</li>
</ul>
<h2>0.4.27</h2>
<ul>
<li>
<p>Add Cargo cfg <code>"span-locations"</code> to expose <a href="https://docs.rs/proc-macro2/0.4/proc_macro2/struct.Span.html#method.start"><code>Span::start</code></a> and <a href="https://docs.rs/proc-macro2/0.4/proc_macro2/struct.Span.html#method.end"><code>Span::end</code></a> accessors that give the line and column location of a Span (<a href="https://github-redirect.dependabot.com/alexcrichton/proc-macro2/issues/166">#166</a>)</p>
<p>Be aware that this involves storing more information than before inside of Spans which increases their size -- leading to possibly slower performance of any code involving proc-macro2 types (but only when the cfg is enabled).</p>

</ul>
