Kristian Bendiksen 3d8912ba6c #14794 Cell filter: Use original parent IJK for IJK range filters on nested hybrid grids
For nested hybrid grids, IJK range filters (I/J/K slices and IJK filters)
now refer exclusively to the original (coarse) grid IJK. Nested-grid local
IJK values are no longer offered, and every cell, including cells in all
refinement levels, is mapped to the original IJK of its top-most parent.

- Add RigNestedHybridGridLayout describing how original cells are embedded
  in the flat grid, shared by the LGR reconstruction and the IJK mapping
- RigMainGrid: store the layout and compute the original IJK of any cell on
  demand by following the parent cell chain, without per-cell storage
- Range filter UI: slider limits, clamping, defaults and active cell range
  use the original grid dimensions; grid selection is hidden
- Evaluate range filters on all grids using the original IJK in the 3D view,
  combined filters and data filters
- 3D view context menu slices use the original IJK of the picked cell
- Add unit tests for the layout, the IJK mapping against OLDIJK, and slice
  filtering across refinement levels
