f42bc45ee8 [wpilib] FlywheelSim cleanup (#6629)
This is a cleanup of the FlywheelSim class with a few added features.

- One FlywheelSim constructor that takes a plant, DCMotor, and a optional number of measurementStdDevs. The documentation now states how to construct the plant either through LinearSystemId.createFlywheelSystem or identifyVelocitySystem.

- The gearbox, gearing and moment of Inertia (J) are now private final fields. The gearing is determined from the plant in the constructor as well as the moment of inertia. There are getter methods that allow the flywheelSim to return the gearbox, gearing, and moment of inertia.

- The getCurrentDrawAmps function now uses m_x instead of getAngularVelocityRadPerSec in accordance with more accuracy and matches the patter in other sims.

- Added getter methods for the InputVoltage, angularAcceleration and torque

- (Java only) A third getter method for returning the AngularVelocity of the flywheel using a MutableMeasure as a backing field that is set when getAngularVelocity is called. This summarily returns the angularVelocity as just a Measure object. This allows the user of this class to handle unit conversions with less numerical manipulation. Alterations in C++ for this feature were not needed.

4bac4dd0f4 [wpimath] Move PIDController from frc2 to frc namespace (#5640)
The old PIDController class in the frc namespace was removed for the
2023 season.

27ba096ea1 [wpilib] Fix MOI calculation error in SingleJointedArmSim (#4968)
Previous calculation derivation mixed up length and distance to CG.

ac9be78e27 Use stricter C++ type conversions (#4357)
Now, implicit narrowing conversions are only used with wpi::Now(). This
also fixes clang-tidy warnings about C-style casts. For example:
```
== clang-tidy /__w/allwpilib/allwpilib/wpilibNewCommands/src/main/native/include/frc2/command/SwerveControllerCommand.inc ==
/__w/allwpilib/allwpilib/wpilibNewCommands/src/main/native/include/frc2/command/SwerveControllerCommand.inc:95:18: warning: C-style casts are discouraged; use static_cast/const_cast/reinterpret_cast [google-readability-casting]
  auto curTime = units::second_t(m_timer.Get());
                 ^
```
In that case at least, the cast was removed entirely since Get() already
returns a units::second_t.

e767605e94 [wpimath] Add typedefs for common types
This makes complex code significantly easier to read.

frc::Vectord<Size> = Eigen::Vector<double, Size>
frc::Matrixd<Rows, Cols> = Eigen::Matrix<double, Rows, Cols>

3f77725cd3 Remove uses of iostream (#4004)
Most of these were unused, the IMU ones were just debug messages.

The only one that wasn't removed is in portable-file-dialogs.cpp since
the replacement looks less trivial.

181723e573 Replace .to<double>() and .template to<double>() with .value() (#3667)
It's a less verbose way to do the same thing.

fe59e4b9fe Make C++ test names more consistent (#3586)
Inconsistent names were found using the following regular expressions.

* `rg "TEST(_F|_P)?\(\w+,\s+\w+Test\)"`
* `rg "TEST(_F|_P)?\(\w+,\s+Test\w+\)"`
* `rg "TEST(_F|_P)?\(\w+Tests,\s+\w+\)"`

Fixes #3495.

9359431bad [wpimath] Clean up Eigen usage
* Replace Matrix<> with Vector<> where vectors are explicitly intended.
  I found these via `rg "Eigen::Matrix<double, \w+, 1>"`.
* Pass all Eigen matrices by const reference. I found these via `rg
  "\(Eigen"` on main (the initializer list constructors make more false
  positives).
* Replace MakeMatrix() and operator<< usage with initializer list
  constructors. I found these via `rg MakeMatrix` and `rg "<<"`
  respectively.
* Deprecate MakeMatrix()

0abf6c9045 [wpilib] Move motor controllers to motorcontrol package (#3302)
Also deprecate SpeedController in favor of motorcontrol.MotorController and
SpeedControllerGroup in favor of motorcontrol.MotorControllerGroup.

The MotorController interface is derived from the SpeedController interface
so that code such as SpeedController x = new VictorSP(1) continues to
compile (just with a warning).

SpeedControllerGroup and MotorControllerGroup are independent classes;
both implement the MotorController interface.
