Revert of Delete video_render module. (patchset #12 id:220001 of https://codereview.webrtc.org/1912143002/ )

Reason for revert:
This breaks every buildbot in chromium.webrtc.fyi and I don't see any roll in progress to address this (and I don't see how that would be possible either).
Usage in Chrome: https://code.google.com/p/chromium/codesearch#search/&q=modules.gyp%3Avideo_render&sq=package:chromium&type=cs

Example failures:
https://build.chromium.org/p/chromium.webrtc.fyi/builders/Linux%20Builder/builds/5420
https://build.chromium.org/p/chromium.webrtc.fyi/builders/Win%20Builder/builds/4526

I think it's fine to delete our video_render_module_internal_impl target and those files, but video_render target needs to remain.

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.

Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.

The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others. This page is maintained by the Google Chrome team.

Development

See http://www.webrtc.org/native-code/development for instructions on how to get started developing with the native code.
