This reverts commita599eeab78, plus follow-upfa4431449d"Avoid bogus loplugin:dllmacro 'unnecessary *DLLPUBLIC declaration ...'". See (abandoned) <https://gerrit.libreoffice.org/#/c/42983/> "loplugin:dllmacro: Handle implicit member functions" how this would have needed to be extended to give consistent results across Linux and macOS, but then would have started to remove DLLPUBLIC from entities that apparently need to at least have default type visibility on macOS and started to make tests fail.
