Without this mValue may end up looking like a valid nsCSSValue object and bad
things will happen when we try to clone it.
We could just assign mem::zeroed() to mValue but this array hacking on the Servo
side is already pretty nasty and mSimulateComputeValuesFailure would still
remain unassigned (and if we did try to assign it on the Servo side we'd need to
only assign it in debug builds). Unless this proves performance-critical, it's
probably best to just do this on the Gecko side.

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.
