QStringConverter/Encoder/Decoder: make move noexcept

The State state data member had non-noexcept move-SMFs, which were
inherited by the move-SMFs of QStringConverter, QStringEncoder and
QStringDecoder.

To fix, because it is called in the move-assignment operator, we need
to mark State::clear() as noexcept, and, since that can perform an
indirect call through clearFn, require the clearFn to be noexcept,
too.

The only users of clearFn were in Qt5Compat; a separate fix should
have been merged there by the time this lands.
