Revert "Reland "Clean up libjingle API dependencies.""

This reverts commit 5117b047875970cf61f2403b590c44c37bfa8272.

Reason for revert: Still breaks downstream projects that include too much stuff.

Original change's description:
> Reland "Clean up libjingle API dependencies."
> 
> This is a reland of 57fb3154b5411934b80051ad827db4e54d00f381
> Original change's description:
> > Clean up libjingle API dependencies.

> > This CL moves candidate.h into the public API, since it has
> > been implicitly included before.
> > 
> > This is a straightforward way of solving the circular

> > libjingle_peerconnection_api includes candidate.h from
> > jsepicecandidate.h, but _api can't depend on rtc_p2p, which
> > depends on _api. In fact, _api can't depend on much at all
