Use vs 2019 for appveyor as well as python 3.9 (#534)

* Visual studio 2019 (instead of 2017)
* Let vcpkg install cgal manage its dependencies (boost, mpfr and gmp)
* vcpkg install tbb also
* need to vcpkg integrate install
* pip installations are no more in --user mode
* Modify all / to \ for windows pths
* Compile python module --inplace, and copy required dll inside gudhi directory (add dll path to windows PATH is not enough)
* Cmake add_GUDHI_PYTHON_lib_dir was not multi-path proof (happens in windows with release_path;debug_path mechanism)
* With CGAL >= 5.3.0, CGAL_HEADER_ONLY CMake variable is no more set as it is the default mode
* GUDHI_PYTHON_PATH_ENV Cmake variable requires ; as path separator on windows, and : otherwise
