fixup! fsmonitor-fs-listen-win32: implement FSMonitor backend on Windows

Let's keep avoiding the `*A()` family of Win32 API functions because
they are susceptible to incoherent encoding problems. In Git for
Windows, we always assume paths to be UTF-8 encoded. Let's use the
dedicated helper to convert such a path to the wide character version,
and then use the `*W()` function instead.
