Eevee: Use manual derivatives for better quality bump.
We basically duplicate the height map branch plugged into the bump node,
and tag each node in each branch as dx/dy/ref using `branch_tag`.
Then we add a one pixel offset on the texture coordinates if the node is
tagged as dx or dy.
The dx/dy branches are plugged into (new) hidden sockets on the bump node.
This match cycles bump better but have a performance impact. Also, complex
nodetrees can now become instruction limited and not compile anymore.
