    tests/gobject/src: Export symbols for MSVC-style builds
    
    Define the decoration macros in the previous commit to __declspec(dllexport) so
    that we can export the test APIs when we build the DLL on Visual Studio-style
    builds.
    
    This includes builds done with clang-cl, in addition to MSVC builds, since
    this will be needed for clang-cl builds.
