It seems that `ScriptInterpreterPython::SharedLibraryDirectoryHelper` can't correctly determine path to liblldb.dll after this change.
`SharedLibraryDirectoryHelper("build-lldb\Lib\site-packages\lldb\native\_lldb.cp312-win_amd64.pyd")` returns `build-lldb\Lib\bin\liblldb.dll` instead of `build-lldb\bin\liblldb.dll`.

This should help:
