Revert of Split iOS sdk in to separate targets (patchset #13 id:280001 of https://codereview.webrtc.org/2862543002/ )

Reason for revert: Breaking downstream projects. Original issue's description: > Split iOS sdk in to separate targets > > This CL splits the iOS sdk into separate static libraries for video, > audio, ui, common, and peerconnection-related code. This will in the > future make it easier to compile WebRTC without unneeded components. > > BUG=webrtc:4867 > > Review-Url: https://codereview.webrtc.org/2862543002 > Cr-Commit-Position: refs/heads/master@{#18166} > Committed: 52c83fe710 TBR=magjed@webrtc.org,denicija@webrtc.org,tkchin@webrtc.org,henrika@webrtc.org,kthelgason@webrtc.org # Skipping CQ checks because original CL landed less than 1 days ago.
