This update for llvm17 fixes the following issues:

- Add symbol versions to libclang-cpp.so similar to libLLVM.so. This is required when multiple versions of the library are loaded into the same process (bsc#1219405, bsc#1221183, bsc#1233220)
- Update llvm17.keyring from upstream
- Correct target name for libomptarget in file list
- Enable lldb on s390x and ppc64le (bsc#1232906)
- Add minor version to Python shebangs (bsc#1212476)
- Require 8 GB memory for 64-bit architectures to prevent OOM
