The implementation of the template function is defined in KeyframeUtils.cpp,
whereas the caller is inside KeyframeEffectReadOnly.cpp. I guess it's been
compiled accidentally because of unified builds.

We have ServoCSSParser class, and I think it's better to move those
Servo FFI into this class to avoid including ServoBindings.h everywhere.

The difference between nsDocument::IsWebAnimationsEnabled and
nsContentUtils::AnimationsAPICoreEnabled is that the former checks the caller
type and treats the preference as set for system callers which is particularly
needed for enabling things like the getProperties() API for DevTools etc.
Generally in API-facing call sites we have a JS context / CallerType and so we
want to distinguish between system callers and non-system callers. However, for
a few internal uses--specifically filling-in missing keyframes--we don't care
about the caller type and always follow the pref setting.
That may or not be quite what we want, but this patch doesn't change that except
for one call site: KeyframeUtils::GetKeyframesFromObject. This patch changes
GetKeyframesFromObject from *not* checking the caller type to checking the
caller type. That seems to be the correct behavior here since this is called
from KeyframeEffectReadOnly::SetKeyframes(JSContext*, JS::Handle<JSObject*>,
ErrorResult&) (i.e. a JS API-facing call site) where we *should* enable the full
API when the caller is chrome code.

There are no reliable steps to make this happen but it appears to have happened
at least twice during fuzzing. As a result, it doesn't matter too much what the
behavior here is as long as we don't crash.

When styling with the Servo backend, we should also use the Servo backend to
determine if a property is animatable or not. However, if we do this,
Servo_Property_IsAnimatable will start returning true for the 'display' property
once we mark that as animatable in Servo (for SMIL).
Even if we later fail to actually animate 'display' (due checks added to Servo
in the next patch) we still need to treat 'display' as un-animatable in
KeyframeUtils so that we don't *read* the 'display' property of Keyframe objects
passed to the Animations API, since that is observable.
This patch makes us consult Servo_Property_IsAnimatable when using the Servo
backend and also explicitly treat the 'display' property as not animatable.

In subsequent patches, the servo version of KeyframeUtils::ApplySpacing()
changes fifth argument to const ServoComputedValues*. If we still use nullptr
for the fifth argument in caller side, compilers can't determine whether
nsStyleContext* or const ServoComputedValues* should be used.

I've propagated quirks mode information on some places. But we needed to pass
quirks mode to some other FFI functions to be able to handle that information
properly.

We need another flag that represents allow-negative-number for SMIL, so
this enum will also comprise the another parsing mode that allows negative number.

We will use this type later in this patch series in nsSMILCSSProperty so this
patch moves it to a separate file so it can be re-used.

This patch does the following in addition to a simple move:
* change the type of the pointers from RefPtr to nsCOMPtr
* move it from mozilla::css namespace to mozilla

Otherwise we hit below assertion in nsCSSValue::DoReset().
MOZ_ASSERT(NS_IsInCompositorThread() || !ServoStyleSet::IsInServoTraversal());
PropertyValuePair.mValue was introduced for computing paced timing in the case
where there is some invalid values in keyframes. Paced timing has been removed
removed from the spec and stylo will not support paced timing. So we don't need
to set the value for stylo.

While we're here, don't re-recompute the default computed values, just grab them
from the device.

Servo_GetComputedKeyframeValues is almost the same as what we do in
KeyframeUtils::GetComputedKeyframeValues() for Gecko. Unlike the function
for Gecko, this function does not allocate each ComputedKeyframeValues element,
the allocation has been done before calling Servo_GetComputedKeyframeValues.
