Add usage reporting for many new things (#2184)

- new CommandScheduler
- kinematics and odometry classes
- new PIDController
- ProfiledPIDController
- TrapezoidProfile (reported in Constraints class)

Also update instances.txt to match latest NI version.

One side effect is that a couple of classes are no longer constexpr.
