Add support for updating static arrays or other static members at runtime

[LyalinDotCom]

During EnC and .NET Hot Reload it would be great to be able to update things such as static arrays.

Below example is from the ASP.NET Core WebAPI default template example around weather. Today you can apply changes but its never re-initialized so it doesn't actually change the runtime state.

Example:

  private static readonly string[] Summaries = new[]
        {
            "Freezing", "Bracing", "Chilly", "Cool", "Mild", "Warm", "Balmy", "Hot", "Sweltering", "Scorching"
        };
