Generate a .NET Framework shim app in dotnet-install-tools on Windows instead of a batch script (#8384)

Implement a simple launcher tool for running new processes on Windows

- This application takes two parameters via the .exe.config configuration file

 - entryPoint: required - the file path to the new process being launched
 - runner: optional - the executable or interpretter used to launch the
entryPoint

- Update dotnet-install-tool to generate an exe instead of a batch script file
