Add evaluation framework

[PhilippvK]

Test generated compiler with patched ETISS. (This should probably be part of a 3rd part repository)

Steps:

• Define VPs used for Evaluation #70
• Setup ETISS & M2ISAR as Evaluation Target #71
• Propose CI/CD Evaluation Flow #72
• Setup Docker for Evaluation #77
• Integrate ETISS & M2ISAR in Evaluation Flow #73
• Integrate Seal5 build in Evaluation Flow #74
• Collect (Smoke) Tests for Evaluation #75
• Collect Benchmarks for Evaluation #76
• Documentation for Evaluation Flow #78
• Publish evaluation scripts?

Work in Progress. Gitlab CI/CD test infrastructure and docker will be used for evaluation.
