Fixes issue with selections in charts.

This addresses several bugs with chart interactions and selections including
BUG #14223, BUG #14224, BUG #14225. We now have two buttons for selection types:
rectangular and polygonal. One presses those to enter selection mode (or use the
corresponding key-board shortcuts). The modifier buttons are don't start/stop
selection, but just affect how the selection is updated on the subsequent
selection action. Selection modifier is persistent and hence persists till user
manually changes it. We switch in and out of selection mode similar to what we
do for 3D view i.e. on mouse-up, we come out selection mode to regular
interaction mode.

BUG #14226: Fix selection on charts + find data

Making pqContextView use the vtkSMSelectionHelper to create new selection proxy
instead of the custom code. The custom code was not working correctly when the
current selection source was not of the expected type. vtkSMSelectionHelper
handles all those cases.

Also removing obsolete code pqSelectionManager for creating selection sources.
Use vtkSMSelectionHelper instead.

rectangular selection.
