f3c70ab9f3 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.

4212451884 [Shader Graph Gen.] Introduce QShaderGraph::Statement 
This is our "byte code" representing a flattened graph. It will be used
as input for the code generation.

29a748511a [Shader Graph Gen.] Introduce QShaderGraph 
This allows to connect our nodes together via ports. This way user code
can assemble a shader from simpler blocks.
