Plugins - don't export internal classes

Plugins are MODULEs not SHARED libraries in cmake terminology and thus
cannot be linked, but instead their intention is to be just loaded
dynamically. Therefore we remove all `Q_MULTIMEDIA_EXPORT` statements on
function definitions which are not the plugin entry points.
