Roll back checking in the third_party directory
This goes back to using a subtree mirror of Chromium's third_party directory (managed by gclient).
The related scripts for syncing the files are also deleted.
The plan is to solve the conflict by creating third_party directories in subdirectories of WebRTC rather than the repo root.
