Reviewed by Darin Adler.
PerformanceTests:
Add new tests for a few aspects of media playback; namely: how quickly media elements fire
the "canplaythrough" event when all data is immediately available, how quickly HLS playback
switches resolutions, and at what playback rate MSE-backed video can play without dropping
frames. Skip these tests by default, as they're not runnable on all ports, and they require
a webserver (run-webkit-httpd) to complete on macOS.
