CI: Decouple Linux image build in build-artifact
Separate the Linux image build process from the build-artifact CI. The Linux image is now majorly built via a workflow dispatch event while ELF artifacts do not need to be built in the same event, thus decoupling these processes ensures that ELF artifacts are not unnecessarily rebuilt. This modular approach improves the flexibility of the artifact building workflow.
