Transform animation in out-of-view element might move in visible area so if we
throttle it the transform animation might come in view suddenly. So we don't
throttle transform animations in ouf-of-view element anymore if it's not
infinite. Finite animations don't last so that they won't consume CPU so much
time.

In TimingParams::CalcActiveDuration(), we intentionally use IsZero() instead
of the bool() operator since the value |aDuration| is Maybe<StickyTimeDuration>
, it's easily misread as Maybe::bool().

We are going to pass animations to the compositor in before phase but not to
pass when active duration is zero. To distinguish this state we need a new
function to check that the active duration is zero.

This is a pre-patch for part 5, which is trying to make our code closer to the
spec. Some methods in KeyframeEffectReadOnly belong to AnimationEffectReadOnly,
so first, use AsKeyframeEffect() to access those keyframe-related methods, and
then add virtual methods for timing-related methods to AnimationEffectReadOnly.

Add two dictionaries into AnimationEffectReadOnly.webidl:
1. AnimationEffectTimingProperties
2. ComputedTimingProperties
And then re-generate this class.
