Generalize V4L2 HW video codec device names

Generalize V4L2 HW video codec device names

Switch to more generalized V4L2 video accelerator device names and update
sandbox rules to reflect that.

After video_ChromeHWDecodeUsed autotest is fixed, this cl is submitted again
due to crrev.com/730693005 reverted in crrev.com/784553004.

BUG=405861, 437598, 439175
TEST=passed video_ChromeHWDecodeUsed with h264 and vp8 on peach_pit.
Media.GpuVideoDecoderInitializeStatus value is 0 when playing a video
from youtube. DUT only has /dev/video-enc and /dev/video-dec device nodes.
