Quick3DShaderDataArray

QML allows property var array: [] of simple types only.
We can't use a var property to store an array of ShaderDataObject so
Quick3DShaderDataArray was introduce to overcome that issue.
It contains a QQmlListProperty<Quick3DShaderData>.

This is only needed for QML, in C++ providing a QVariantList of QShaderData is
enough.
