Type get type generic annotation test (#2071)

Add a test that if a gener parameter has annotation and the type with that parameter is referenced via `Type.GetType`, the annotation gets applied.
There is already a test for `string` data flow handling in `ApplyTypeAnnotations.TestFromConstantWithGeneric`, but there was no test for `Type.GetType` (which uses slightly different codepath in the product).
