Fix deprecation warnings in PhotonLib examples (#1699)

The following deprecation warnings have been fixed:
- `SwerveModuleState.optimize(desiredState, currentRotation);`, which is
now an instance method
- `AprilTagFields.kDefaultField.loadAprilTagLayoutField();`, which is
now `AprilTagFieldLayout.loadField(AprilTagFields.kDefaultField);`

WIP:
- [x] C++
- [x] Python
