.Net Core - Update example to self host the BrowserSubProcess

Eliminates the requirements for .Net 4.5.2, the application exe is used as the browsersubprocess.
Additional manual import of CefSharp.BrowserSubProcess.Core is required see csproj file for example

TODO: OffScreen version is crashing on exit so it's been updated, it just isn't using itself as the BrowserSubProcess
