#14345 Add per-case cell filter evaluation with source case override

Add a sourceCaseOverride parameter to RimCellFilter::applyToCellVisibility.
When set, property filters evaluate against the override case's result
values instead of the case the filter is bound to, allowing the same
filter definition to be evaluated against each case in an ensemble.
Combined filters forward the override to their children, and geometry
based filters ignore it.

Add RimCellFilterTools::computeReservoirCellVisibility, which evaluates
a cell filter against a given case for all grids and returns the
visibility indexed by reservoir cell index. Range filters propagate the
parent grid visibility into LGR cells, matching the filtered geometry
of a 3d view.

Also add RimCellFilter::setFilterMode.
