I'm surprised that this passed the CI on Windows, because
Q_AUTOTEST_EXPORT is Q_DECL_EXPORT, which is __declspec(dllexport) and
all dllexport'ed functions must be defined in the current DLL, not
imported from elsewhere. This is similar on Unix systems with the
no_direct_extern_access mode, because then Q_DECL_EXPORT behaves like on
Windows.
That means Qt modules can't call a Q_AUTOTEST_EXPORT function
from another module (only tests can). Solve this by providing a function
that is properly exported with Q_CORE_EXPORT.
Amends commit 3d08816f4c4245f08a53307775fe3c4ed31a7a32.
