[lldb][Windows] Only embed Python home in Debug config (#209464)
On Windows, we used to embed `PYTHONHOME` by default on Windows. In the
documentation, we say
> This is most useful for developers who simply want to run LLDB after
they build it.
Since we use the limited/stable API now, we're less restricted in the
Python version, so I think it's less of an issue that LLDB won't find
Python. The only configuration where it might cause issues is the debug
configuration, since, when installing Python, you usually don't include
the debug libraries. Thus, you might not have the debug version
(`python3_d.py`) of Python in your PATH.
