Histogram drag/drop and paste improvements (#12851)

* Add drag'n'drop support for ensemble summary vectors and ensembles into histogram plots

* Make sure histogram plot is shown and all update signals are connected when loading a project.

* Support ensemble parameter drag'n'drop from data sources into histogram plots. 

* Show ensemble parameters in data sources tree.

* Add copy/paste of histogram curves

* Re-use all existing parameters in a plot when dragging a new ensemble into it
