[Chromecast] Adds Browser test for media playback

This is the best mechanism I can find for testing overlay video frame
creation and usage (something which can easily be broken right now).
It also makes up for the recent loss of the cma end to end test.

The overlay frames are still broken (fixing in a separate CL), so this
includes a couple of tweaks to handle the breakage more gracefully and
fall back to black frames.  Once overlays are fixed, that can be
replaced with some stronger assertions.
