#14524 Histogram: Auto-select logarithmic binning and show filter info text

Select logarithmic binning and a logarithmic x-axis automatically when creating a
grid statistics histogram plot from a 3D view showing a logarithmic result
(RiaResultNames::isLogarithmicResult).

Show a plot info label at the top right of the plot canvas describing active data
filters: "Filter: Visible cells in 3D view" when a cell filter view is set, and
"Filter: User defined x-range [min..max]" when the bin range is user-defined. The
label collects unique filter descriptions from the data sources of all visible
curves and is removed when no filters are active.
