QParameter: only copy QNodeId when parameter value is a QNodeSubclass

This avoid doing useless clones and will be further improved to support
UBO/SSBO when Buffer are used as a Parameter's value.

QNode subclasses that can be used as the value of an attribute are:
QAbstractTextureProvider -> default uniform block
QShaderData -> UBO (could be made to work with SSBO as well)
Buffer -> UBO / SSBO
