Artifact Script Update

[Casperento]

This pull request significantly restructures the Docker build process for the LLVM test suite experiment. The previous manual build and test steps have been replaced with a more automated workflow using the daedalus-dbg-toolkit and a custom LLVM build with the func-merging pass. The new approach streamlines experiment setup and execution, integrating external repositories and scripts for improved reproducibility and maintainability.

Experiment automation and workflow update:

• Removed manual CMake build, test, and comparison steps for the LLVM test suite, including explicit configuration for baseline and Daedalus runs.
• Added cloning of the daedalus-dbg-toolkit repository and installation of its Python dependencies to automate experiment orchestration.
• Introduced cloning and building of a custom LLVM fork (code-size branch) with the func-merging pass, enabling new experimental capabilities.
• Replaced individual build and test commands with execution of the run-experiment.sh script from the toolkit, passing all required paths and options for a unified experiment run.
