Adapt ci pipelines (#5)

* Remove unnecessary workflows

- CIFuzz requires additional setup at the google service
- MacOS and Windows are irrelevant for s-core
- We will setup our own documentation

* Replace 'latest' compiler versions by an exact version

- 'latest' compilers may lead to irreproducible results
- current v3.12.0 does not run without errors with 'latest' compilers
- Remove very old clang compilers (<17) as the corresponding old docker images lead to errors
- ci_static_analysis_clang target needs to use clang 18 or newer because of new compiler flags
