This commit rewrites the internal `version` module that exported various information about the current executable. Instead of exporting several consts, we are now exporting a single const structure that contains all the necessary information. This is the first step towards cleaning up how we use this information and should allow us to use SUI to be able to patch this information in already produced binary making it easier to cut new releases. --------- Co-authored-by: Divy Srivastava <dj.srivastava23@gmail.com>
