Add multi-arch Docker build support and Makefile targets

This update enhances the Docker build workflow to support multiple architectures (amd64, arm64, armv7, ppc64le, riscv64, s390x) using buildx and matrix builds in GitHub Actions. The Makefile now includes new targets for building and exporting artifacts for each supported architecture. The Dockerfile is updated to allow conditional use of custom Conan profiles via a new USE_CUSTOM_PROFILE build argument.
