[SDA] Avoid initializing a deferred start time based on a potentially stale timeline.

Previously, the start time of an animation could be initialized during
the update snapshot phase as well as the snapshot validation phase.
The snapshot is stale during the update snapshot phase if a layout
dependency is introduced during style-update.

The stale start time will get corrected during snapshot validation;
however, we can trigger unexpected animationstart or animationend
events based on the stale start time. We prevent this, but only
initializing the start time during snapshot validation.
