sebastien lussier ab2422f434 Fixed PolyGroup issue with FMeshMergeHelpers::MergeImpostersToMesh() ...

The function would remap polygroups of the source meshes, then use  FStaticMeshOperations::AppendMeshDescription() which would also mess with the groups.

Providing a polygroup delegate to AppendMeshDescription() solves the issue.
