Detailed Description

Counters for within-step track initialization and activity.

When running device code, these counters are now updated on the device throughout the step, so they are stored in TrackInitStateData. They need to be synchronized between the host and device before and after the step to maintain consistency.

For all user StepActionOrder (TODO: this may change if we add a "user_end"), all but the secondaries/alive counts are for the current step iteration, and secondaries/alive values are from the previous step iteration.

Todo:

Drop the 'num' prefix since we know they're counters.
