[glib/resources.msvc] gresources: Add a test with resources > 64kb



commit 8038b7a6fec556d3ed5e9af95402f04ec6dcd962
Author: Chun-wei Fan <fanchunwei src gnome org>
Date:   Fri Nov 30 17:49:44 2018 +0800

    gresources: Add a test with resources > 64kb
    
    This is to ensure that the generated code is still compilable by the
    running compiler, and see whether we can read the things in there
    properly.
    
    See issue #1580.
