Introduce WebRTC component build.

This CL switches all the Chromium dependencies from being direct
dependencies on WebRTC targets to a WebRTC component (which lives
at //third_party/webrtc_overrides:webrtc_component).

From now on, Chromium should never directly depend on WebRTC in
order to avoid issues explained at [1] (this will be guarded
by checkdeps and GN visibility (see [2])) but should only depend
on the WebRTC component.

This should solve a broad range of problems caused by WebRTC being
linked in different shared libraries when is_component_build=true
(from globals and singletons causing hard to debug issues, to ODR
violations and binary size increase).
