qtdeclarative: define QT_FEATURE_quick_sprite (fixes QtQuick #if div-by-zero)

quick_sprite was the one QtQuick feature missing from qtquick-config_p.h (10
others defined), so any consumer including the private scenegraph headers hit
'#if QT_CONFIG(quick_sprite)' -> 1/QT_FEATURE_quick_sprite with the macro
undefined -> 'division by zero in #if'. This blocked qt5compat's GraphicalEffects
QML module (and would block every QtQuick-based QML module across the Plasma
stack). Enable -DQT_FEATURE_quick_sprite=ON alongside the other quick_* features.
