adb / libbase: clean up NOGDI and evil ERROR macro

Instead of defining and undefining NOGDI:

1. Always #include "base/logging.h" after #include <windows.h>.
Unfortunately, I could not find an easy way to give the user a
warning/error if they include in the wrong order.

2. base/logging.h does #undef ERROR to undefine the evil ERROR macro
that is from another era and probably a bad idea to begin with.
