vtkChartXY: for non-identity ShiftScale transforms in vtkPlotPoints
vtkChartXY::LocatePointInPlots() was redundantly rescaling the nearest point location by the plot's ShiftScale property when the mouse was over a plotted point, resulting in the incorrect point location information being displayed in the tooltip. Remove the redundant rescaling so that the tooltip displays the correct information.
This fixes paraview/paraview#21022 (closed)
Backport: paraview/release
