qdoc: Remove Q_QDOC for qRound() and qRound64()

These uses of Q_QDOC cause clang to report syntax errors.
They are used to hide function return values as qreal
instead of using double and float. The decision is to be
more transparent and use double and float in the docs
instead of qreal.

This change does not require clang in qdoc.
