Lower the priority of shared workers that aren't associated with the foreground tab.
This should help out less powerful devices in the case where there's a shared worker in another tab and a cpu intensive page in the foreground.
BUG=
TEST=Open a doc, see webworker running, switch tabs and check webworker's priority by outputting contents of /sys/fs/cgroup/cpu/chrome_renderers/background/cgroup.proc on ChromeOS. With an open doc in a background tab, run 720p video (ie. youtube) at fullscreen, should stay fairly smooth.
