Bazel client: make it compile with MSVC

Final modifications to the Bazel client code so
we can compile //src/main/cpp/...:all using MSVC.
Yay!

We still have some dependencies that don't compile
with MSVC, namely Ijar, build-runfiles,
process-wrapper, and process-tools.

Still, this change is a huge success, because now
we can add regression tests to prevent people from
introducing breaking changes to the client that
would break Windows/MSVC compilation.

It's important to point out that we can only build
this library for now, most functions in
file_windows.cc and blaze_util_windows.cc have an
empty body (they just call `pdie`).
