Only prompt once when setting multiple block opacities

This fixes a bug in which the opacity dialog would open for
each block when changing the opacity for multiple blocks. Now,
only a single opacity value dialog will be used and that opacity
will be set on all the selected blocks.

Remove obsolete pqPickHelper class.

The class doesn't seem to be compiled since a while (I believe it was replaced
by pqRubberBandHelper).

BUG #14046: Fixing issues with interaction modes and multiple views.

The use pqRubberBandHelper between multiple views was causing weird interaction
issues with selection modes, picking and such. Refactored the code to deprecate
pqRubberBandHelper. Instead, we now use pqRenderViewSelectionReaction to assist
with selection modes for the render views. Cleaned up usage of
pqRubberBandHelper to use the new refactored code.

Leaving pqRubberBandHelper for backwards compatibility. It should be removed in
future versions.
