win: Formally disallow cl.exe
cl.exe moved to "community supported" a while ago, but nobody seems to
be interested in maintaining this build configuration, so formally stop
supporting it.
We'll keep around most of the gn file goop for it (for v8 and angle and
other projects that use Chromium's gn files and want to keep supporting msvc),
but we'll stop supporting it in chromium itself.
