Magne Sjaastad c1cf37b792 #14906: PolygonFilter: Invalidate cached cells on case change and guard cell index
Crash signature 43cb673b7481.

RimPolygonFilter::updateCellIndexFilter writes visibility using cached m_cells indices without a bounds check. The cache is cleared only in onGridChanged(), so when the Eclipse case changes to a grid with fewer cells the stale indices write past the end of the array.

Override setCase() to clear the cached cells, and skip indices outside the visibility array.
