[llvm] [lldb][Windows] add release notes for the Python private API removal (PR #209456)

[Charles Zablit via llvm-commits]

https://github.com/charles-zablit created https://github.com/llvm/llvm-project/pull/209456

The official lldb releases set `LLDB_EMBED_PYTHON_HOME` to `OFF` https://github.com/llvm/llvm-project/blob/9582f71a3b5f71e871bee0062e641f3587e0ae23/llvm/utils/release/build_llvm_release.bat#L213 meaning that lldb on Windows does not use the private Python API by default. Users are free to use any Python version they want. Add a release note for this.

 * LLDB now uses `lldb-server.exe` to launch and manage the program being debugged,
