Reverts Chromecast using external V8 snapshot files.

Reverts Chromecast using external V8 snapshot files.

This currently breaks at runtime both cast_shell and cast_shell_apk
and I wasn't able to find an easy fix. I'd like to unblock our other development in the meantime.

TBR'ing jochen@ on the revert to unblock.

It's essentially a revert of https://codereview.chromium.org/1019123002/, but
only reverting the Chromecast part.

lgtm (thanks for reverting only chromecast). I'll take a look at what's going
wrong before trying to reland.
