Remove the lies WebMediaPlayerImpl is telling V8.

Remove the lies WebMediaPlayerImpl is telling V8.

Removing hacky code that sends made up data to V8 to trick it into running
GC more often. This was added a long time ago and it is unlikely it is
actually helping things anymore. Removing this code also eliminates
WebMediaPlayerImpl's dependency on V8 which helps with moving this code
to media/blink.
