For method TypeConverter GetConverter(object component, bool noCustomTypeDesc),
Type.GetType() is naively used to resolve TypeConverter types and thus
Type.GetTypeConverter often just returns null.

component.GetType().Assembly.GetType(typeName) ??
should be used (this appears to be the ms.net behavior).

Reproducible: Always

Steps to Reproduce:
1. Create a type say MyType and apply
[TypeConverter("MyNamespace.MyTypeConverter")] to the type. Do not specify the
name of the assembly.
2. Call TypeConverter.GetTypeConverter(new MyType(), false)
Actual Results:  
The TypeConverter type is not resolved (null is returned), thus the
TypeConverter is not applied.

Expected Results:  
The TypeConverter type should be resolved and returned.
