This creates a valid Python API for Windows, pending some issues. The changes included are -

- Ported the SWIG wrapper shell scripts to Python so that they would work on Windows too along with other platforms
 - Updated CMake handling to fix SWIG errors and manage sym-linking on Windows to liblldb.dll
 - More build fixes for Windows

The pending issues are that two Python modules, termios and pexpect are not available on Windows.
These are currently required for the Python command interpreter to be used from within LLDB.
