Reland: Enable ServiceWorkerPerformanceTimeline flag for stable
This ships User Timing and Resource Timing in Workers, and workerStart
attribute of Resource Timing.
This is a reland of r197722, which is reverted in r199493 to avoid
shipping prefixed Resource Timing APIs. That has been addressed in
r200301; now only unprefixed version of the APIs are available in worker
contexts.
Intent to Implement and Ship:
