  [web-animations] add the notion of an "intrinsic iteration duration" from Web Animations Level 2

Reviewed by Dean Jackson.

Web Animations Level 2 introduces the notion of an "intrinsic iteration duration"
in https://drafts.csswg.org/web-animations-2/#intrinsic-iteration-duration. We
need to introduce this notion in our codebase to support Scroll-driven Animations
since the simple "iteration duration" may use seconds values which would cause problem
since all progress-based values are expected to be percentages.
