GPUNodeTree: Add weight tree inversion

This constructs a "mirror" nodetree that feeds the closure "shader"
nodes with their respective final weight.

The tree is mirrored using simple math nodes. This is quite messy but
this is the only way to proceed without introducing special nodes.
The other issue with this method is that inputs are all uniforms even
for unplugged socket on temporary math nodes with add bloat to the
shader uniform buffer structure.

Only the part relevant to the weighting is duplicated. Other connexions
with the shading tree are reuse.

All shader nodes are updated to receive a `Weight` hidden parameter.

The original shader mixing tree is preserve to let the choice of using
either way to weight the output.

For now this is only done for the output nodes. This will need to be
extended to Closure to RGBA sub-tree.
