Improve display name when DataRow contains arrays

[Evangelink]

Summary

When the DataRowAttribute contains multiple items including at least one array, then the display name will display the type instead of unwrapping the values.

Example

public void GetDisplayNameForMultipleArraysOfOneItem()
{
	// Arrange
	var dataRow = new DataRowAttribute(new[] { "a" }, new[] { "1" });
	var methodInfoMock = new Mock<MethodInfo>();
	methodInfoMock.SetupGet(x => x.Name).Returns("MyMethod");

	// Act
	var displayName = dataRow.GetDisplayName(methodInfoMock.Object, dataRow.Data);

	// Assert
	Verify(displayName == "MyMethod (System.String[],System.String[])"); // Expecting `MyMethod ([a],[1])`
}

public void GetDisplayNameForMultipleArraysOfMultipleItems()
{
	// Arrange
	var dataRow = new DataRowAttribute(new[] { "a", "b", "c" }, new[] { "1", "2", "3" });
	var methodInfoMock = new Mock<MethodInfo>();
	methodInfoMock.SetupGet(x => x.Name).Returns("MyMethod");

	// Act
	var displayName = dataRow.GetDisplayName(methodInfoMock.Object, dataRow.Data);

	// Assert
	Verify(displayName == "MyMethod (System.String[],System.String[])"); // Expecting `MyMethod ([a,b,c],[1,2,3])`
}

We will expose a protected property on the DataRowAttribute that let subclasses know what's the selected TestIdGenerationStrategy and we will use this property to condition the change and avoid any breaking change.
