    meson: Install msvc_recommended_pragmas.h on Windows
    
    Copy the msvc_recommended_pragmas.h helper header when we build for
    Windows, so that people developing/using GLib on Windows can make use
    of them in Visual Studio, so that unwanted compiler noise can be
    filtered out and code with potentially-problematic warnings can be
    attended to.
