Implement time:* 4.0.0 commands (#736)

* Abstract SteadyClockCore to follow Nintendo changes in 4.x

This is the ground work for 4.0.0 support

* Implement TickBasedSteadyClockCore

Preparation for the ephemeral clock.

* Refactor SystemClockCore to follow 4.0.0 changes

* Implement EphemeralNetworkSystemClock

* Implement GetSnapshotClock & GetSnapshotClockFromSystemClockContext

* Implement CalculateStandardUserSystemClockDifferenceByUser & CalculateSpanBetween

* Remove an outdated comment & unused import

* Fix a nit and GetClockSnapshot

* Address comment
