Implement beta IVRInput system for testing

In order to test new system:

Build and deploy application.

Copy both files from IVRInput/ dir into the bin/win64 folder.

Change const std::string m_actionManifestPath in steamivrinput.h to be
directly to your action_manifest.json file.

Run and turn on a Vive controller. Press the menu button. If logs say
"NEXT SONG SET!" it works.
