#6922 Generate svg from domain diagram headless

It should be possible to generate the svg diagrams headless e.g. via ant.
This makes it possible to generate modvis animations or documentation on the build server.

The headless svg build was based on the GLSP. This is the preliminary stage for later editing the Actifsource editors via Theia VsCode or Native in the browser.

BuildConfig 'SvgdomainDiagramHeadlessBuildConfig'






On github the example has been extended:
