[Python] Remove Python include from ScriptInterpreterPython.h
This patch limits the scope of the python header to the implementation of the python script interpreter plugin. ScriptInterpreterPython is now an abstract interface that doesn't expose any Python specific types, and is implemented by the ScriptInterpreterPythonImpl. Differential revision: https://reviews.llvm.org/D59976 llvm-svn: 357307
