Per bug 1322570 Comment 7, we could drop the GetParentAllowServo() when we
invoke UpdateProperties() from a SquentialTask, so allow it for now.

nsStyleContext::CalcDifference had an optimization where, when we knew
that the old and new style context have the same rule node, we knew that
the only change hints that would need to be handled are those in the
"not handled for descendants" category, generated due to explicit
'inherit' values on reset properties. This was because any changes due
to differences in inherited properties should only have generated
"handled for descendants" change hints (and thus would already have been
handled on an ancestor).
Before bug 931668, this let us avoid calling CalcDifference on structs
that only would have generated hints that we knew we already would have
handled. However, after bug 931668, we compare all structs anyway so
that we can set the aEqualStructs outparam, so we don't gain anything
from this optimization. We can still return these change hints we know
will not need to be handled, and rely on ElementRestyler::CaptureChange
to filter them out.

Before this patch, we store each computed values in a hashtable,
nsRefPtrHashtable<nsUint32HashKey, RawServoAnimationValue>, for all
KeyframeEffectReadOnly on an element, and convert the ServoAnimationValues of
the hashtable into an nsTArray<ServoAnimationValue*> and then convert
the ServoAnimationValues of the nsTArray into PropertyDeclarationBlock
in rust. This way was really inefficient.
In this patch, we store the computed values into AnimationValueMap and
convert all AnimationValue in the map into PropertyDeclarationBlock
after EffectCompositor::GetAnimationRule.

Later in this patch series we will replace ServoAnimationRule with a hashmap.
At that point, we would like to pass the hashmap to ComposeStyle. In order
to achieve that, this patch templatizes the 'animation rule' parameter of
ComposeStyle in both Animation and KeyframeEffectReadOnly so that it can
represent a hashmap instead.

We no longer need separate time for cascade levels respectively since we do
send all type of animations on the same element to the compositor regardless
of cascade level.

We convert nsStyleContext* to servo's computed values in UpdateProperties()
since it is called from various places (e.g. SetTarget()) with nsStyleContext*.
MozReview-Commit-ID: KxPjm82Crl
We had to implement UpdateProperties(nsStyleContext*) explicitly
since there are some calls of UpdateProperties() with RefPtr<nsStyleContext>.
Without this compiler tries to use template function instead.

We'd like to use template to manage functions that have almost the same functionality
both on stylo and gecko instead of branching in each functions because it will be
easier to maintain stylo and gecko for a while.

To avoid using StyleAnimationValue on stylo, we should skip
ApplySpacing, which means We always fall back to distribute spacing on stylo.

EnsureBaseStyle() requires an already resolved nsStyleContext
and resolves the base style by ResolveStyleByRemovingAnimation().

Move the implementation of uncomputing to string into AnimationValue,
and add one more FFI for RawServoAnimationValue.

1. Call Servo's interpolation from KeyframeEffectReadOnly::ComposeStyle().
2. Store the results into ServoAnimationRule.
MozReview-Commit-ID: LOp2mbXforg
1. Introduce ServoAnimationRule, which is an equivalent of AnimValuesStyleRule.
2. Wrap ServoAnimationRule and AnimValuesStyleRule into a struct, and
use it as the parameter of Animation::ComposeStyle and
KeyframeEffectReadOnly::ComposeStyle.
3. Uncompute the RawServoAnimationValues in ServoAnimationRule when we
need it.

Based on the other changesets in this series, we don't expect to be calling
UpdateProperties() and ComposeStyle() from within ComposeStyle() itself.
However, in case there is some scenario where that does still occur, we leave
the mIsComposing check in place and add an equivalent MOZ_DIAGNOSTIC_ASSERT so
that we are alerted if this does occur on debug / Nightly / DevEdition builds,
but handle it gracefully on beta or release builds.

Test case, 1330190-2.html, is another variant of 1325193-1.html. It's for
animation on a pseudo element, causes timeout without part 3 patch.
