Revert of Add clang-format binaries and scripts for all platforms

third_party/clang_format/README.txt

-This folder contains clang-format binaries. The binaries will be automatically
-downloaded from Google Storage by gclient runhooks for the current platform.
-
-For a walkthrough on how to maintain these binaries:
-  https://code.google.com/p/chromium/wiki/UpdatingClangFormatBinaries
-
-To upload a file:
-  python ~/depot_tools/upload_to_google_storage.py -b chromium-clang-format <FILENAME>
-
-To download a file given a .sha1 file:
-  python ~/depot_tools/download_from_google_storage.py -b chromium-clang-format -s <FILENAME>.sha1
-
-List the contents of GN's Google Storage bucket:
-  python ~/depot_tools/third_party/gsutil/gsutil ls gs://chromium-clang-format/
-
-To initialize gsutil's credentials:
-  python ~/depot_tools/third_party/gsutil/gsutil config
-
-  That will give a URL which you should log into with your web browser. The
-  username should be the one that is on the ACL for the "chromium-clang-format"
-  bucket (probably your @google.com address). Contact the build team for help
-  getting access if necessary.
-
-  Copy the code back to the command line util. Ignore the project ID (it's OK
-  to just leave blank when prompted).
