The wrapper includes reverse mode autodiff, the Problem DSL, and the
optimal control problem API. I wrote it by directly translating the
upstream
[API](https://github.com/SleipnirGroup/Sleipnir/tree/main/include/sleipnir)
and [tests](https://github.com/SleipnirGroup/Sleipnir/tree/main/test) to
Java (i.e., copy-paste-modify).
I replaced the ArmFeedforward and Ellipse2d JNIs with implementations
using the Sleipnir Java bindings. Switching dev binary JNIs to release
by default sped up wpimath test runs from several minutes to 7 seconds.
I left "free speed" alone since that's the technical term for it. In
general, velocity is a vector quantity, and speed is a magnitude (i.e.,
a strictly positive value).
This PR also replaces the speed verbiage in MotorController with duty
cycle.
Fixes#8423.
ChassisAccelerations and the drivetrain acceleration types are added in
both Java and C++. `ChassisAccelerations` is basically just
`ChassisSpeeds` but for accelerations!
`DifferentialDriveWheelAccelerations`, `MecanumDriveWheelAccelerations`,
and `SwerveModuleAccelerations` are the acceleration equivalent of the
drivetrain speeds types.
In Java, the `Kinematics` interface now has an additional generic
parameter `A` which represents the accelerations, and
`toChassisAccelerations` and `toWheelAccelerations` methods, which are
implemented the same way as `toChassisSpeeds` and `toWheelSpeeds`.
Protobuf and struct classes were also added for all four classes in Java
and C++.

* Moved makeWhiteNoiseVector() to random.Normal.normal()
* Moved isControllable() and isDetectable() to system.LinearSystemUtil
* Renamed makeCostMatrix() to costMatrix() (Java)
* Renamed makeCovarianceMatrix() to covarianceMatrix() (Java)
* Renamed MakeCostMatrix() to CostMatrix() (C++)
* Renamed MakeCovMatrix() to CovarianceMatrix() (C++)
* Removed deprecated poseTo3dVector(), poseTo4dVector(), poseToVector()
* Removed clampInputMaxMagnitude()
* We don't use it, and Eigen has this functionality built in via `u =
u.array().min(u_max.array()).max(u_min.array());`
* Simplified implementation of desaturateInputVector()
