[WIP] Allow vectorization types to be used with dune-geometry
This branch builds on dune-common!81 (merged). It makes it possible to stuff vectorized types from some vectorization library into the templates provided by dune-geometry.
See also: dune-common!81 (merged), dune-istl!17 (merged).
[WIP] Check that it still works with current dune-common (i.e. do a unit test).
