video: Add PlayDecodeAccelUsed* tests

video.PlayDecodeAccelUsed* tests are corresponding to
video_ChromeHWDecodeUsed.* in autotest.

video.PlayDecodeAccelUsed(H264|VP8|VP9) play videos and
check if hardware video decoder was used.
This CL doesn't include autotest's video_ChromeHWDecodeUsed.*.mse
tests, which we decided to change the way of testing.

BUG=chromium:900102
TEST=tast run eve video.PlayDecodeAccelUsed*
TEST=tast run veyron_jerry video.PlayDecodeAccelUsedVP9
     and get error because of lack of VP9 hardware decoder.

video: Add PlayDecodeAccelUsedMSE*

video.PlayDecodeAccelUsedMSE(VP8|VP9|H264) tests are corresponding to
video_ChromeHWDecodeUsed.(vp8|vp9|h264).mse in autotest.
These tests check if video can be played properly when Media Source
Extensions (MSE) is used.

While the autotest version accessed crosvideo.appspot.com, the Tast
version use Shaka Player to run tests offline.
Shaka Player plays video streams by using MPEG-DASH.

video.PlayDecodeAccelUsed*, which is Tast version of video_ChromeHWDecodeUsed, were added.
The remaining task is removing "informational" label to run them on Chrome OS CQ.
So, let me modify the summary of this issue.
