fix: update to Newbluecake/bootstrap v0.17.1 for LLVM 17+ support

- Replace deprecated go-clang/bootstrap v0.14.0 with Newbluecake/bootstrap v0.17.1
- Update all imports from github.com/go-clang/bootstrap to github.com/Newbluecake/bootstrap
- Fix CI generator failures due to LLVM version mismatch
- Update CI to use clang 18 to match new bootstrap version

The go-clang/bootstrap project only supports LLVM 14, which was causing
undefined symbol errors (CXCursor_OMPArraySectionExpr) when running with
newer clang versions. The Newbluecake fork supports LLVM 17+ and resolves
these compatibility issues.
