Original change's description:
> Make sure Chromium will pick the correct field_trial/metric impl.
>
> Chromium wants to pick its own field_trial and metrics implementation,
> and WebRTC has an escape hatch to let it remove the definition of these
> symbols. This obviously causes liker errors if Chromium will not pick
> the correct dependency (which cannot be forced by GN check since there
> is no header inclusion).
>
> Instead of hoping that the build target with the correct implementation
> will be added as a dependency somewhere in the build graph, this CL
> wants to explicitly add the dependency as close as possible to the
> headers, so if they are included and WebRTC is built as part of Chromium
> the correct implementation will be linked into the binary.
