Reviewed by Tim Nguyen.
Since accelerated effects may be accessed both via the main thread and the
scrolling thread on macOS,
the `TimingFunction` class should use `ThreadSafeRefCounted` like all the other
ref-counted types used
by `AcceleratedEffect` and `AcceleratedEffectValues`.
This fix was automatically suggested by an LLM during bug analysis, I validated
its approach.
