Revert of Fix autoplay during prerendering for media elements on Android. (patchset #4 id:60001 of https://codereview.chromium.org/1293253003/ )
Reason for revert:
https://build.chromium.org/p/chromium.linux/builders/Linux%20Builder%20%28dbg%29/builds/92412/steps/compile/logs/stdio
This CL seems redefining MediaBrowserTest, which is already defined in chrome/browser/media/media_browsertest.h
and causing build breakage.
Original issue's description:
> Fix autoplay during prerendering for media elements on Android.
>
> If the user gesture for autoplay is disabled manually or via an
> experiment, prerendered media will play in a hidden frame.
>
> Within WebMediaPlayerImpl this behavior is deferred at load time
> via a callback, however WebMediaPlayerAndroid was never given
> this callback, so it would try to play media. Generally this
> fails because by default autoplay requires a user gesture.
>
> The correct fix is to refactor WMPA such that it uses a params
> structure like WMPI and can invoke the deferral callback when
> load() is called.
>
> BUG=522157
> TEST=clank no longer plays hidden a/v when user gesture disabled.
