#13806 Python: Add color legend scripting API

Expose RimColorLegendCollection and RimColorLegend to Python via
CAF_PDM_OBJECT_METHOD entries that let callers create a legend, append
category items with a hex-string color, bind a legend to a (case,
resultName) pair and delete that binding.

Scriptable fields on RimColorLegend and RimColorLegendItem make the
created objects inspectable from Python.

The (case, resultName) binding interface in RimColorLegendCollection,
RimRegularLegendConfig and RimEclipseCellColors now takes a const RimCase*
instead of a case id, matching the caller patterns and avoiding ambiguity
when multiple cases share an id domain.
