Implement graph layers support in QShaderGraph

When creating the statements, it is now possible to pass a list of
enabled layer names. Every node or edge which is not in the list of
enabled layers will be pruned from the graph prior to traversal. Note
that an empty layer list for a node or an edge means it is on all
layers.
