Integrate the new GLSP Standard Feature for Alignment helper lines and remove the current custom impl

See :

• Alignment helper lines #621
• https://github.com/eclipse-glsp/glsp-client/pull/306

Implementation example:

    bind(TYPES.ISnapper).toConstantValue(new BPMNElementSnapper());
    bind<IHelperLineOptions>(TYPES.IHelperLineOptions).toConstantValue({
        alignmentElementFilter: element =>
            isBPMNNode(element),
        minimumMoveDelta: { x: 10, y: 10 }
    });

....

export function initializeBPMNDiagramContainer(container: Container,
    ...containerConfiguration: ContainerConfiguration): Container {
    return initializeDiagramContainer(container, bpmnDiagramModule, bpmnHelperLineModule, BPMNPropertyModule, ...containerConfiguration);

}
