QFilesystemWatcher/Windows: Use event dispatcher of thread
Previously, the native event filter listening on removable drivers
was installed on QCoreApplication::eventDispatcher() which led to
a mismatch when launched from a non-GUI thread since
~QAbstractNativeEventFilter() removes itself from
QAbstractEventDispatcher::instance().
