    meson.build: Ignore warning C5030 on Visual Studio
    
    We are now using C++17 attributes in place of the GLib macros as needed, so we
    can ignore warning C5030 that comes from attributes that are not recognized by
    the compiler, in particular the GCC-specific ones, since they simply not apply
    for Visual Studio builds.
    
    (cherry-picked from commit f80a945e)
