[lldb] clean up lldb/scripts a little bit

[hhb]

Summary

No functional change.

Without testing, the changes LGTM. However, please wait for Pavel to review this as well.

I don't think this is fully right. We did have a separate xcode build, but it was removed a couple of months ago. Instead the regular cmake build supports building a macos-style framework (and I believe it does that regardless of which generator is used). So all that's needed here is to replace references to xcode with some blurb about "frameworks", and instead of "built by llvm" we should just say that we're building with a traditional unix layout. @sgraenitz might know more details here...

     Overview:       Python script(s) to post process SWIG Python C++ Script

-                    The Python scripts are equivalent to the shell script (.sh)
-                    files.
                     For the Python script interpreter (external to liblldb) to
                     be able to import and use the lldb module, there must be
                     two files, lldb.py and _lldb.so, that it can find. lldb.py
                     is generated by SWIG at the same time it generates the C++
                     file.  _lldb.so is actually a symlink file that points to
                     the LLDB shared library/framework.
                     The Python script interpreter needs to be able to
                     automatically find these two files. On Darwin systems it

                     We use SWIG to create a C++ file containing the appropriate
                     wrapper classes and functions for each scripting language,
                     before liblldb is built (thus the C++ file can be compiled
                     into liblldb.  In some cases, additional work may need to be
                     done after liblldb has been compiled, to make the scripting
                     language stuff fully functional.  Any such post-processing
                     is handled through the Python scripts called here.
