Implement HasResize

The following discussion from !1546 (merged) should be addressed:

• @timok started a discussion:

  I think has resize is also needed in other places. Theoretically we can just use a copy of https://web.math.pmf.unizg.hr/nastava/nrpdj/DuneDoc/release-2.6.1/dune-functions/doc/doxygen/html/a01948_source.html the implementation in dune functions and put it e.g. in dumux/common/concepts.hh

Also some other tiny "concepts" might be useful, however usually it's not real concepts so we should be careful.
