- G4Navigator:
* Added missing implementation of SetVoxelNavigation method (i.e. VecGeom Nav.)
* deleted experimental method RecheckDistanceToCurrentBoundary (obsolete)

* cleaned up ComputeSafety
- G4VoxelNavigation:
* simplify code of 'check' mode tests -- avoid 2nd code path.

at marginal extra cost in check mode (extra call to DistanceToOut)
* added comments about method arguments.
