  [web-animations] keyframes should be recomputed if a custom property registration changes
https://bugs.webkit.org/show_bug.cgi?id=251509

Reviewed by Antti Koivisto.

If the registration of a custom property is changed, we must recompute keyframes of any effects
with keyframes targeting that custom property. To that end, we add a new method on KeyframeEffect
that the CustomPropertyRegistry can call into to notify the change of a custom property's
registration.
