Geometry Nodes: Resolve some missing 3D viewport updates

These two functions "snode_notify" and "ED_node_tag_update_id" appear to
be mostly duplicates. However, there is already a case for each type of
built-in node tree, so it makes sense to add one for the geometry node
tree as well. This doesn't solve the update issues for changing number
in buttons, that must be handled somewhere else.

Merge branch 'master' into geometry-nodes

Geometry Nodes: Add edge split node functionality

Geometry Nodes: expose minimum vertices input of Triangulate node

Fix error in previous commit

That should not have happened -.-

Fix previous comment

Geometry Nodes: simplify and deduplicate callbacks on sockets

This adds a layer of abstraction between the code calling callbacks
on sockets and the implementation of those callbacks.
This abstraction layer allows some sockets to not implement all
callbacks when those can be derived from some other callback.

Geometry Nodes: change "Node Tree" to "Node Group"

Geometry Nodes: initial support for evaluating geometry node groups

This is still very basic and does quite a few unnecessary computations.
Also the error handling is quite weak currently, so when invalid things are
connected, it will probably just crash.

Also the interface that individual nodes have to implement will have to change,
but the current solution is a good starting point.

Only the triangulate node is implemented for now.

Geometry Nodes: add an initial geometry class

Functions: add generic pointer class

This class represents a pointer whose type is only known at runtime.

Functions: add move operations to CPPType

Geometry Nodes: Add initial node definition for edge split

This is just based on rBa7dba81aab22, and contains no funcionality at all.

Merge branch 'master' into geometry-nodes

Nodes: add initial UI for Triangulate node

Merge branch 'master' into geometry-nodes

Nodes: improve dependency between modifier and node group

Nodes: support creating geometry node groups

Nodes: show header in geometry node editor

Modifiers: add node_tree to NodesModifierData
