This should fix some trybot flakiness we've seen today.
Original commit message:
[infra] Update Clang toolchain and GN
We no longer rely on Fuchsia's buildtools, instead we directly fetch
Clang and GN packages from CIPD using gclient support.

To build Dart for Mac and Linux, we pull Fuchsia's buildtools, which is also used by Flutter. Fuchsia's buildtools includes gn, and the clang toolchain. Fuchsia buildtools vends clang-format as part of the clang toolchain. Since Fuchsia's buildtools doesn't vend a clang toolchain for Windows, we can't get a Windows clang-format binary from it. Therefore, from Chromium's buildtools here:
https://chromium.googlesource.com/chromium/buildtools
we copy the hash file for its Windows clang-format binary, and pull it down from google storage in the update.py script in this directory.
To update to a newer Windows clang-format binary, simply overwrite the hash in clang-format.exe.sha1 with a newer one, and then do a 'gclient sync'.
