widl: Avoid adding duplicate type definitions if tag and typedef names are the same.

Fix handing of the following .idl snippet: typedef [uuid(b14b6bb5-904e-4ff9-b247-bd361f7a0001)] struct g { int g1; } g; [uuid(b14b6bb5-904e-4ff9-b247-bd361f7a0002)] interface test_iface : IUnknown { HRESULT test([in] g *ptr); } Signed-off-by: Dmitry Timoshkov <dmitry@baikal.ru> Signed-off-by: Huw Davies <huw@codeweavers.com> Signed-off-by: Alexandre Julliard <julliard@winehq.org>
