[gobject-introspection/msvc-pragmas-stable: 1/2] giscanner/scannerlexer.l: Include io.h on Windows

commit 4357f98b838d91a61fd4c99f3dc2f3bfbd130fc5

    giscanner/scannerlexer.l: Include io.h on Windows
    
    This is to compensate the for the lack of unistd.h on Visual Studio
    builds, and to avoid the compiler warning about the implicit declaration
    of access() as a result.  This is to also prepare for the next commit
    when we force-include msvc_recommended_pragmas.h from GLib on Visual
    Studio builds.
