Make QByteArrayView's numeric conversion methods inline
Make the implementations of these methods free functions in the
QtPrivate namespace, so that they can be called also from
QByteArrayView's corresponding inline methods.
These methods were added in 6.3, so we can still make them inline
without breaking BC.
Fixes: QTBUG-101077
Pick-to: 6.3
