Subject: [PATCH] Add Fuchsia clang and sdk to DEPS

These use CIPD (from depot_tools) to download packages created by the
Fuchsia team. The .ensure file is passed to `cipd` which currently
include specificiations for the Fuchsia team's build of clang (which,
because it's close to HEAD includes support for targeting Fuchsia), as
well as the Fuchsia SDK.

Both packages are specified as "latest" rather than pinning to a
specific revision. At this early point in the process we don't have any
good reason to pin, but that can be accomplished later by replacing that
with a specific package's SHA1.

Due to the (relatively new) 'condition': 'checkout_fuchsia', this DEPS
step will only be run when .gclient includes 'fuchsia' in the target_os
block at the top_level, e.g.

$ cat .gclient
solutions = [
  { ...  },
]
target_os = ['fuchsia']
