Allow different ElementMapper types in ElementIndexScatterHandle.

Browse Source 
This is needed to support dune-fem where the local mapper might
be
`MultipleCodimMultipleGeomTypeMapper<GridView<GridPart2GridViewTraits<AdaptiveLeafGridPart<CpGrid, (PartitionIteratorType)4,
false> > >, Dune::Impl::MCMGFailLayout>`
as opposed to the global one being
`MultipleCodimMultipleGeomTypeMapper<GridView<DefaultLeafGridViewTraits<CpGrid>>, Dune::Impl::MCMGFailLayout>`.

Closes #2095.
