[lldb] Use PY_VERSION_HEX to simplify conditional compilation (NFC) (#114346)

Use PY_VERSION_HEX to simplify conditional compilation depending on the
Python version.

This also adds a static_assert to lldb-python to error out with a
meaningful diagnostic when you try building LLDB with an older Python
version in preparation for [1].
