win: Explicitly disable symbols on bots using goma.
With MSVC, goma implicitly disables symbols in compiler.gni. With clang,
that isn't the case, so when we enable clang by default, it currently
also implicitly enables debug info on all bots using goma. Explicitly
turn off symbols on these bots. With MSVC, that's no behavior change,
and it makes sure symbols stay off when we enable clang.
