#13890 Faults: Add FAULTDIST result for a user-selected subset of faults

The existing FAULTDIST result always considered every fault in the main
grid. Users with many faults need to compute distance fields against a
named subset, so this adds a Fault Distance Results collection under
each view's Faults node. Each entry holds a multiselect of faults and a
name (FAULTDIST1, FAULTDIST2, ...) and publishes the result into the
Generated cell-result category.

The per-cell BVH-based distance loop was extracted from
RigFaultDistanceResultCalculator into a reusable utility that accepts
the subset of faults to include; the original all-faults entry point
delegates to the same utility and keeps the static-native FAULTDIST
behavior unchanged.
