Reviewed by Matt Woodrow.
Make `RemoteMonotonicTimeline` opt into thread-safe ref-counting. This fixes
the following tests
when "Threaded Time-based Animations" is enabled:
- fast/animation/css-animation-throttling.html
-
webanimations/combining-transform-animations-with-different-acceleration-capabilities-6.html
