Expose cxx constructor and method properties through libclang and python bindings.

Summary:
I have exposed the following function through libclang and the clang.cindex python bindings:

clang_CXXConstructor_isConvertingConstructor,
clang_CXXConstructor_isCopyConstructor,
clang_CXXConstructor_isDefaultConstructor,
clang_CXXConstructor_isMoveConstructor,
clang_CXXMethod_isDefaulted

I need (some of) these methods for a C++ code model I am building in Python to drive a code generator.
