[Web Animations] Implement the procedure to set the target effect of an animation
https://bugs.webkit.org/show_bug.cgi?id=183146
Reviewed by Dean Jackson.
We only had a partial implementation of setEffect() and we now update it to cover the entire
implementation as mandated by the spec. While this doesn't yield any WPT results changes, this
patch will help getting a significant number of new PASS results when we get around to implement
correct support for async procedures (pending pause/play tasks and promises) in the next patch.
