Revert 63176 - Fix regression where high resolution timers could be activated even under
battery power. Add unit test to protect chromium from developers like me
in the future.
The fix is a one-liner in hi_res_timer_manager_win.cc. The rest of the code
change is the mechanics to enable the unit test.
BUG=59528
TEST=HiResTimerManagerTest.ToggleOnOff
