  [scroll-animations] update animation procedures to set the "auto align start time" flag

Reviewed by Dean Jackson.

The Web Animations Level 2 specification introduces the "auto align start time" flag for
animations associated with a non-monotonic / progress-based timeline, such as a scroll
timeline. We update the various existing procedures to account for this new flag, in
preparation for the implementation of the "auto-aligning the start time" procedure
(https://drafts.csswg.org/web-animations-2/#auto-aligning-start-time) in a future patch.
