Autolinking for C++ projects only generates AutolinkedNativeModules.g.cpp, not the header file

[jonthysell]

Problem Description

The header file is necessary, and while it doesn't really change when autolinking is run, autolinking should still (re)create the file, as it may have been deleted by the end user (or missing for another reason) and we claim in the file that it gets generated by the autolink command, when it clearly isn't.

Steps To Reproduce

1. Create a new C++ RNW project.
2. Delete AutolinkedNativeModules.g.h
3. Run autolink-windows or run-windows

Expected Results

The file gets recreated.
