Do not require member type in [DynamicData] when member is defined on base class

[Evangelink]

Summary

Make usage as simple as possible when member info can be inferred.

Background and Motivation

The use case below should be simplified:

public class Base
{
    public static IEnumerable<object[]> GetData() => yield return new object[] { 1 };
}

[TestClass]
public class MyTest : Base
{
    [TestMethod]
    [DynamicData(nameof(GetData), DynamicDataSourceType.Method)] // MSTEST0018 + error at runtime
    public void M(int i) {}
}

Proposed Feature

Do not require the typeof when we know the member is part of the class (through inheritance).
