COMP: Update vtkAddon and remove redundant Markups MRML classes

The class `vtkSlicerDijkstraGraphGeodesicPath` was originally integrated
into Slicer by @Sunderlandkyl through Slicer/Slicer@0a730a747 (ENH: Update
surface tracing for markup curves) with additional contribtions from
@lassoan, @jamesobutler and @hjmjohnson.

The classes `vtkCurveGenerator`, `vtkLinearSpline` and
`vtkParametricPolynomialApproximation` were originally integrated into
Slicer by @lassoan and @Punzo through Slicer/Slicer@23d076495 (ENH: Reworked
markups fiducials and added line, angle, and curves) with additional
contribtions from @Sunderlandkyl, @cpinter, @jcfr, @jamesobutler, @phcerdan and
@hjmjohnson.
