It looks like according to https://buildkite.com/llvm-project/libcxx-ci/builds/29381#018a5138-767f-4472-9fcb-c20da396c5c2, we are missing `PythonAndSwig` from the Docker image.

```
Could NOT find PythonAndSwig (missing: Python3_LIBRARIES
-- Python3_INCLUDE_DIRS LLDB_ENABLE_SWIG)
```

How do you generally install it?
