Automatic update from web-platform-tests [OT-PW] Animation integration with new CC impl This CL is for Off-thread PaintWorklet animation integration described in this design doc: https://docs.google.com/document/d/1a7gO6cBxsJhn53akuJuieUiXvB74vvEmFDyKww8NKdw/edit# Right now this CL handles composited custom property animations only, handling native properties should be simpler. Also, right now we only support custom properties that represent numerical values. Here is a summary of the main changes: A new class AnimatedPaintWorkletTracker is created and LTHI keeps an instance of it. The new class maintains a hashmap such that when CC animation ticks, LTHI is able to update the custom property values for corresponding PaintWorkletInput. And also that when LTHI needs to dispatch paint job to the worklet thread, it is able to identify which paint worklets are dirty. Other changes are mostly plumbing needs associated with the above changes.
