Revert of "Android MediaCodecVideoDecoder: Manage lifetime of texture frames" https://codereview.webrtc.org/1378033003/

The code that depends on the reverted CL is disabled but not removed. NativeHandleImpl is reverted to the previous implementation, and the new implementation is renamed to NativeTextureHandleImpl. Texture capture can not be used anymore, because it will crash in peerconnection_jni.cc.

Reason for revert:
Increased HW decoder latency and crashes related to that. Also suspected cause of video tearing.

Original issue's description:
> This CL should be the last one in a series to finally
> unblock camera texture capture.
>
> The SurfaceTexture.updateTexImage() calls are moved from
> the video renderers into MediaCodecVideoDecoder, and the
> destructor of the texture frames will signal
> MediaCodecVideoDecoder that the frame has returned. This
> CL also removes the SurfaceTexture from the native handle
> and only exposes the texture matrix instead, because only
> the video source should access the SurfaceTexture.
