Pull in Rust toolchain via util/bot/DEPS

Use gclient with the condition 'checkout_rust' to pull in the
update_rust.py script from Chromium. Add a hook to run update_rust.py
to download a copy of the Rust toolchain from GCS.

Because update_rust.py depends upon the tools/clang/scripts/update.py
script, this modifies the condition for boringssl/util/bot/tools/clang
to also fetch the clang script whenever we 'checkout_rust' (but it does
not need to actually run tools/clang/scripts/update.py).

BoringSSL

BoringSSL is a fork of OpenSSL that is designed to meet Google's needs.

Although BoringSSL is an open source project, it is not intended for general use, as OpenSSL is. We don't recommend that third parties depend upon it. Doing so is likely to be frustrating because there are no guarantees of API or ABI stability.

Programs ship their own copies of BoringSSL when they use it and we update everything as needed when deciding to make API changes. This allows us to mostly avoid compromises in the name of compatibility. It works for us, but it may not work for you.

BoringSSL arose because Google used OpenSSL for many years in various ways and, over time, built up a large number of patches that were maintained while tracking upstream OpenSSL. As Google's product portfolio became more complex, more copies of OpenSSL sprung up and the effort involved in maintaining all these patches in multiple places was growing steadily.

Currently BoringSSL is the SSL library in Chrome/Chromium, Android (but it's not part of the NDK) and a number of other apps/programs.

To file a security issue, use the Chromium process and mention in the report this is for BoringSSL. You can ignore the parts of the process that are specific to Chromium/Chrome.
