    Meson: Ignore more warnings on Visual Studio
    
    We can safely ignore warnings C4251, C4273 and C4275 as we are sure that we
    want to use __declspec(dllimport) on the libraries that we depend upon, and
    even with the C++11 versions, we are basically tied to the same CRT as Visual
    Studio 2015 or later is required to build the C++11 branches of the the -mm
    dependencies fully.
    
    We can also ignore warning C4805 since a 'gboolean' is defined to mimic a
    'bool'.
