WebRTC: Build Chromium with codecs

WebRTC: Build Chromium with codecs

In order to build and test the OpenH264 codec, we need
to pass additional GYP_DEFINES variables to our bots.
These are already used by several bots in Chromium, but 
mainly by the GPU team.
OpenH264 is not yet built when they're defined, but the
plan is to make it so soon, so we want to ensure we're
building with it since Chromium tests marked as MANUAL_
are going to be added, which only run in these 
WebRTC-controlled waterfalls.

The GN bots are handled by the MB config in
https://codereview.chromium.org/1654953004/

BUG=576201

I discussed with hbos@ to make use of the already existing property called
proprietary_codecs instead of the use_openh264 in Chromium. So that's why I'm
enabling them here.
hbos@ will make a CL that changes the behavior in the src-repo.
