7269a170fb Upgrade maven deps to latest versions and fix new linter errors (#3772)
This also makes the Gradle build work with JDK 17.

The extra JVM args in gradle.properties works around a bug with spotless
and JDK 17: https://github.com/diffplug/spotless/issues/834

PMD.CloseResource was ignored because it's almost always a false
positive, and there are many of them.

2cb171f6f5 [docs] Set Doxygen extract_all to true and fix Doxygen failures (#3695)
The template argument order for UnscentedTransform was reversed to match
all the other UKF classes. Since UnscentedTransform is intended as a
class for internal use only, this shouldn't cause much breakage.

187f50a344 [wpimath] Catch incorrect parameters to state-space models earlier (#3680)
This allows giving more descriptive exceptions than if they are thrown
later in KalmanFilter, for example.

Fixes #3678.

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()

aa3848b2c8 [wpimath] Move RobotDriveBase::ApplyDeadband() to MathUtil (#3529)

3b5d0d141a [wpimath] Add LinearFilter::BackwardFiniteDifference() (#3528)
This is an alternative to #2344 that handles arbitrary order derivatives
of arbitrary precision. The downside is that since it's part of
LinearFilter, it can't utilize the units type system in the same way to
make Calculate()'s input type different from its output type.

50af74c38f [wpimath] Clean up NumericalIntegration and add Discretization tests (#3489)
* Rename Butcher tableau sections in NumericalIntegration such that
  top-left is c, top-right is A, and bottom-right is b
* Move edu.wpi.first.math.Discretization to
  edu.wpi.first.math.system.Discretization
* Sort Java Discretization to match C++ function order
* Add tests for Java Discretization
  * Required adding Runge-Kutta time-varying impl to tests
* Move C++ Runge-Kutta time-varying impl to tests only
  * Users don't need it

1daadb812f [wpimath] Implement Dormand-Prince integration method (#3476)
Also refactored RKF45 implementation to match the new style, which is
easier to read.

The tests were switched from RKF45 to RKDP since it's more accurate.

c1e128bd5a Disable frivolous PMD warnings and enable PMD in ntcore (#3419)
Some valid warnings like throwing NullPointerException or using a for
loop instead of System.arraycopy() were fixed.

Abstract classes marked with PMD.AbstractClassWithoutAbstractMethod were
made concrete because they already had protected constructors.

Fixes #1697.

resize() member function.

15c521a7fe [wpimath] Fix drivetrain system identification (#3406)
The units for angular Kv and Ka were inconsistent with the derivation. A
second factory function overload was added for angular units that uses a
trackwidth to convert to the other form.

Notice how section 15.2 of https://file.tavsys.net/control/controls-engineering-in-frc.pdf
defines the angular feedforward as u = Kv,angular v instead of u = Kv,angular + omega.
The units cancel for elements of A but not B, so just the B matrix was incorrect in our code.

This breaks existing C++ code since the units are part of the function
signature.
