Move include of config.h from source to some header files

This follows dune-common!1313 (merged) to remove all the config.h includes in sources files, since they are not needed anymore. Just a few includes in header files were added for flags that are still in the config.h file but are used only in very few places.

mentioned in merge request dune-common!1313 (merged)

The two preprocessor defines I have found in the code are:

• HAVE_LAPACK (defined in dune-common-config.hh)
• DUNE_ENABLE_PYTHONMODULE_PRECOMPILE (defined in dune-common-config.hh)

Except for the versions, the dune-geometry config.h file does not define anything new.
