plasma-framework QML deps: enable org.kde.config + Qt5Compat.GraphicalEffects

plasma-framework's ecm_find_qmlmodule REQUIRED checks need two QML modules that
were not being built:
- org.kde.config: kf6-kconfig had -DKCONFIG_USE_QML=OFF -> enable it (qtdeclarative
  is already a dep).
- Qt5Compat.GraphicalEffects: qt5compat only builds its QML imports when QtQuick
  is present in the sysroot; add qtdeclarative to qt5compat deps so it cooks after
  QtQuick exists, then stages the GraphicalEffects qml module.
Also declare qt5compat as a plasma-framework dep. (X11/XCB/OpenGL are optional on
the Wayland build and not the blocker.)
