src: include internal/options in the snapshot

This patch enables internal/options to be included in the snapshot, so that when lazy loading the run time options, the modules only need to make sure that the options are queried lazily and do not have to lazy load the internal/options module together. We can still guarantee that no run time options are serialized into the state-independent bootstrap snapshot with the assertion inside GetCLIOptions().
