Use staged builds to minimize final image size

So that redundant things do not end in final image: - Git repo history - Test directories - Git tool and its deps And drop explicit installation of: - jemalloc & GLX: nothing uses them (in ChatQnA at least), and for testing it's trivial to create image adding those on top: https://pytorch.org/tutorials/recipes/recipes/tuning_guide.html#switch-memory-allocator - langchain_core: GenAIComps install langchain which already depends on that This demonstrates that only 2-3 lines in the Dockerfiles are unique, and everything before those can be removed with a common base image.
