[libclang] Introduce clang_Cursor_getObjCSelectorIndex() function.

After getting a cursor with clang_getCursor for a particular source location,
allows querying the cursor in order to find out if the location points to a
selector identifier in an objc method or message expression, and which selector index it is.
