openscenegraph: add v3.4.0, v3.4.1; add '+ffmpeg' (#16360)

* openscenegraph: add v3.4.0/3.4.1, update versioning to use git, improve dependency handling (esp. for ffmpeg, opengl)

* openscenegraph: add '+ffmpeg' variant, add 'jasper' dependency, clean up cmake config variables

* openscenegraph: reverted fetches to use checksums to improve reliability

* openscenegraph: add a few more explicit dependencies (e.g. png, tiff, glib).
