    Remove Py_TPFLAGS_CHECKTYPES
    
    According to 'git annotate', the Py_TPFLAGS_CHECKTYPES was added to
    python-internal.h way back when gdb was first ported to Python 3.  It
    was a compatibility fix for Python 2.
    
    This is not needed any more, because Python 2 is no longer supported.
    This patch removes the vestiges.
