* Fix 9.0.0 related services bindings This was wrong because of a mistake on switchbrew. * Fix wronog cmdid for ISteadyClock::GetTestOffset/SetTestOffset * Update ClockCore logics to 9.0.0 Also apply 9.0.0 permissions and comment time:u, and time:a (as those are going to be moved) * Move every clocks instances + timezone to a global manager * Start implementing time:m Also prepare the skeleton of the shared memory * Implement SystemClockContextUpdateCallback and co * Update StaticService to 9.0.0 * Update ISystemClock to 9.0.0 * Rename IStaticService and add glue's IStaticService * Implement psc's ITimeZoneService * Integrate psc layer into glue for TimeZoneService * Rename TimeZoneManagerForPsc => TimeZoneManager * Use correct TimeZoneService interface for both StaticService implementations * Accurately implement time shared memory operations * Fix two critical flaws in TimeZone logic The first one was the month range being different fron Nintendo one (0-11 instead of 1-12) The other flaw was a bad incrementation order during days & months computation. * Follow Nintendo's abort logic for TimeManager * Avoid crashing when timezone sysarchive isn't present * Update Readme * Address comments * Correctly align fields in ISystemClock * Fix code style and some typos * Improve timezone system archive warning/error messages * Rearrange using definitions in Horizon.cs * Address comments
