Setup github action to build native image binaries of the module generator CLI

[PerryAJ]

GH provides actions that execute on specified platforms. We should use this to run graal native image builds of the CLI, and store each one as part of a 'release' here in github, so that anyone interested may download a fully functional CLI executable and create their own modules.

• Setup Github Action to build native images on Windows, Linux, and Mac
• Add Readme instructions on using the non-native image 'application' build product
