Propose empty mock implementation for replacement target method

In Cheat Sheet, we explained that how a replacement target method will be represented as Indirection Delegate. However, when you use actually, you probably can't notice soon the little difference -- the case that non-public signature type exists, the difference between an instance method and a static method and so on -- even if it is wrong. To avoid that, I think it is better that an empty mock implementation is proposed at the same time as getting Indirection Stub Setting. For example, the following are our expected results:

`public static DateTime Now { get; }` of `System.DateTime` in `mscorlib`

<!--
    PDateTime.NowGet().Body = 
        () => 
        {
            throw new NotImplementedException(); 
        };
-->
<add name="NowGet" alias="NowGet">
  <RuntimeMethodInfo xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns:x="http://www.w3.org/2001/XMLSchema" z:Id="1" z:FactoryType="MemberInfoSerializationHolder" z:Type="System.Reflection.MemberInfoSerializationHolder" z:Assem" xmlns:z="http://schemas.microsoft.com/2003/10/Serialization/" xmlns="http://schemas.datacontract.org/2004/07/System.Reflection">

    <GenericArguments i:nil="true" xmlns="" />
  </RuntimeMethodInfo>
</add>

This is one of the most simple result.

`public static T Exchange<T>(ref T location1, T value) where T : class` of `System.Threading.Interlocked` in `mscorlib`

<!--
    PInterlocked.ExchangeOfTTRefT<T>().Body = 
        (ref T location1, T value) =>
        {
            throw new NotImplementedException(); 
        };

Generic parameter will be proposed as it is, because Prig cannot know that it will be replaced to another.

`internal unsafe static bool TryParse(string s, DateTimeFormatInfo dtfi, DateTimeStyles styles, ref DateTimeResult result)` of `System.DateTimeParse` in `mscorlib`

Non-public signature will be proposed by comment, because they cause a build failure.

`internal virtual string InternalToString()` of `System.Exception` in `mscorlib`

This is the example of a instance method of a class.
