Accurately implement steady & system clocks (#732)

* Improve SteadyClock implementation accuracy * Rewrite system clocks to be accurate * Implement IStaticService 100 & 101 * Add time:* permissions * Address comments * Realign TimePermissions definitions * Address gdk's comments * Fix after rebase
