Reland of Delete video_render module. (patchset #1 id:1 of https://codereview.webrtc.org/1923613003/ )

Reason for revert:
Chrome's build files have now been updated, see cl https://codereview.chromium.org/1929933002/

Original issue's description:
> 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.
