Disable Common Lisp / UFFI target language

Clean up to disable target languages that have been neglected/not functional.
Target language be fully deleted in SWIG 4.1 unless a new maintainer brings
it up to an acceptable status (experimental or supported).

 **     Add shadow class support for the Swindle system. 
 
-Common Lisp
------------
-
-*      Random thoughts by mkoeppe on supporting Common Lisp implementations:
-
-       There are many different Foreign Function Interfaces (FFI) for
-       the various CL implementations.  Probably SWIG should interface
-       to UFFI, a least-common-denominator FFI that supports many
-       implementations.
-
-       Via the s-expression SWIG module we can export SWIG's parse
-       tree and import it into CL.  It remains to check if all
-       relevant information is dumped (for instance, the type
-       information).  Experimental code is available to generate
-       low-level UFFI declarations from this parse tree.
-
-       However, for wrapping C++, we also need to create C wrappers
-       because most FFIs cannot directly import C++.  A CL SWIG module
-       could be exporting both these wrappers and UFFI declarations.
-       I have experimental code (not checked in yet) that does this.
-
-       This is fine for generating low-level wrappers. But how do we
-       support user typemaps (like converting lists and vectors to C
-       arrays on input)?  We have to generate Lisp code that does the
-       conversion and then calls the low-level wrapper.  If we
-       generate Lisp code, it should be beautiful and readable.
-       Therefore, we need at least a Lisp pretty printer.  A Lisp
-       pretty printer works best when the Lisp program is represented
-       not as text but as Lisp data.  Moreover, typemap writers will
-       feel very much constrained by SWIG's capabilities for
-       generating wrapper code, when compared to writing Lisp macros.
-       Thus we would need half a re-implementation of Lisp in SWIG to
-       make users happy.
-
-       The solution could be the following:
-
-**     Build a SWIG library (again) and load it into a Common Lisp
-       implementation.
-
-       The FFI declarations could be written manually, or this could
-       be bootstrapped via the s-expression module or the primitive
-       UFFI wrappers.  This should be easy because SWIG's API is quite
-       simple. 
-
-       The embedded SWIG would be driven by a CL program.  High-level
-       typemaps would be written as Lisp programs that generate Lisp
-       code.
