Add performance test for background video playback.

This will give us BattOr power measurements to use to assess the benefits of the optimizations.

The above code solves this problem for desktop, but the same code does not work for Android because the feature on Android is behind a flag (--disable-media-suspend). This cannot be trivially implemented for Android because we cannot set a flag for a single page on Android: we have to set the flag either at the benchmark level or at the measurement level. 

The blocking bug for this is https://github.com/catapult-project/catapult/issues/3863.

This is fixed, but we should verify that the numbers on https://chromeperf.appspot.com/report?sid=4b3ec844421ebb4628bcfc06235d72efdb188f2424bb5f3cf96fa97da50733fc end up being what we expect. (They should go up now that playback won't be completely suspended on Android for background test.)
