Extracted cleanup from QCoreApplication::exec() into separate function

Not all Qt integration points can call QCoreApplication::exec(), in
particular, ActiveQt. When an ActiveQt server is loaded, it tries to
mimic the behavior of calling QCoreApplication::exec() by setting
QCoreApplicationPrivate::in_exec = true. However, when unloading the
DLL it is necessary to call the same clean-up (e.g. deferred delete)
that QCoreApplication::exec() does. Extracting the cleanup in a separate
function means implementation does not have to be duplicated.
