Boris Chiou ccc24f9fa1 Bug 1737920 - Part 1: Create ViewTimeline when specifying view-timeline property. r=emilio
However, We don't lookup the object of view-timeline-name for CSS animations
until we finish its implementation in the patch series.

Note: this patch assumes `view-timeline-inset` is not animatable. We will
fix it in Bug 1817073.
