qquaternionanimation.cpp: Fix warning suppression

Quote the option, fixing g++ 8.3 warning about:
qquaternionanimation.cpp: In member function ‘void Qt3DCore::Quick::QQuaternionAnimation::setType(Qt3DCore::Quick::QQuaternionAnimation::Type)’:
qquaternionanimation.cpp:147:44: warning: missing option after ‘#pragma GCC diagnostic’ kind [-Wpragmas]
 QT_WARNING_DISABLE_GCC(-Wcast-function-type)                                            ^
qquaternionanimation.cpp:148:107: warning: cast between incompatible function types from ‘QVariant (*)(const QQuaternion&, const QQuaternion&, qreal)’ {aka ‘QVariant (*)(const QQuaternion&, const QQuaternion&, double)’} to ‘QVariantAnimation::Interpolator’ {aka ‘QVariant (*)(const void*, const void*, double)’} [-Wcast-function-type]
         d->interpolator = reinterpret_cast<QVariantAnimation::Interpolator>(&q_quaternionNlerpInterpolator);
