          Fix DesignerAttributeTests failures caused by facade assemblies on .N…

e8e0a09

…ET Core

Two issues caused 3 DesignerAttributeTests to fail with 'No data found':

1. Assembly.Load for .NET Framework names like 'System.Drawing' and
   'System.Design' resolves to facade assemblies on .NET Core that contain
   only TypeForwardedTo entries but no actual types. Fix: add ResolveAssembly
   helper that maps known assembly names to real implementation assemblies
   via type anchors (typeof(Control), typeof(Image), typeof(ControlDesigner)).

2. xUnit v3 non-serializable data handling: when the first [MemberData]
   source yields zero items and the data is not xUnit-serializable, xUnit
   reports 'No data found' without enumerating subsequent sources. Fix:
   reorder [MemberData] attributes so SystemWindowsForms (which always has
   data) comes before SystemDrawing/SystemDesign (which may be empty).
