Subject: [PATCH] I#453 - build: Make it possible to override C++ standard ][

Use target_compile_features() instead of global C++ standard variable,
which allows to define minimum version for the target, instead of forcing
certain version for the whole project.

Closes https://gitlab.gnome.org/GNOME/evolution-data-server/-/issues/453
