Windows, protoc: create io_win32.{h,cc}
Create dedicated files for the long-path-aware
Windows implementations of open/access/mkdir.
This commit updates many BUT NOT ALL usages of
<io.h> functions in protobuf's code base. Reason
being is that there are no Bazel build rules for
the unittest files that include <io.h>, so I
decided to leave those alone.
Thanks to this commit I can now build Bazel with
MSVC without needing a short --output_user_base.
Fixes https://github.com/bazelbuild/bazel/issues/2634
