Initial implementation of PerformanceLongAnimationFrame.

  • Added IDL for PerformanceLongAnimationFrame
  • Added main infrastructure to measure long frames, without support
    for scripts (yet).

How it works:

  • PerformanceMonitor keeps track of whether the current task
    belongs to the current frame tree (same LocalRoot).
    Note that PerformanceMonitor has an instance per LocalRoot.

  • If a task ends without pending updates, report it as a long
    frame only to frames within the same LocalRoot.

  • Otherwise, keep track of the start time and report to all
    affected frames when the frame has done rendering
    (right after intersection observers, before
    painting/compositing).

Next steps:

  • Add support for scripts
  • Generate UKM data from this, to be examined while trying out the
    API.
