Cpp.ignoretokens, Cpp.ignoredirectives, falsehoods are not
used anymore by clang based qdoc.
Most defines are not needed, either, because clang based qdoc
will get these defined by scanning the normal headers. And QDOC,
Q_CLANG_QDOC is actually set by qdoc itself.
What's left is Q_GUI_LIB, Q_WIDGETS_LIB, which is used in headers
modules to make some API conditionally available. Finally, there's
QT_KEYPAD_NAVIGATION, which seems to be a Qt 3 thing, but still
some documentation depending on it ;)
Pick-to: 6.4
