Merge branch 'master' into greasepencil-object

GPencil: Improve Bake Animation to Linked

Also allows to bake several meshes at the same time.

GPUVertexFormat: Add Rename function

This is needed for motion blur.

bring back a break

handle node tree in lib_query.c

GPUVertBuf: Add duplication function

allow using shader texture nodes in simulation node tree

Add emitters, events, forces and control flow socket types

This is part of T73324.

The shapes and colors of the sockets will most likely change later on.

This script can be used to create a node with the new socket types:
```
import bpy

class MyCustomNode(bpy.types.Node):
bl_idname = 'CustomNodeType'
bl_label = "Custom Node"

def init(self, context):
self.inputs.new('NodeSocketEmitters', "Emitters")
self.inputs.new('NodeSocketEvents', "Events")
self.inputs.new('NodeSocketForces', "Forces")
self.inputs.new('NodeSocketControlFlow', "Control Flow")

self.outputs.new('NodeSocketEmitters', "Emitters")
self.outputs.new('NodeSocketEvents', "Events")
self.outputs.new('NodeSocketForces', "Forces")
self.outputs.new('NodeSocketControlFlow', "Control Flow")

bpy.utils.register_class(MyCustomNode)

if len(bpy.data.simulations) == 0:
bpy.data.simulations.new("Simulation")

sim = bpy.data.simulations[0]
sim.node_tree.nodes.new("CustomNodeType")
```

GPencil: Use BKE function to get mesh_eval

New Object and Image socket types

The main difficulty with adding these types is that they are the first sockets types
that reference ID data in their `default_value`. That means that I had to add some
new logic in a few places to deal with reference counting. I hope I found all the places...
It seems to work fine in my tests.

For now these socket types can only be created using a script like the one below:
```
import bpy

class MyCustomNode(bpy.types.Node):
bl_idname = 'CustomNodeType'
bl_label = "Custom Node"

def init(self, context):
self.inputs.new('NodeSocketObject', "Object")
self.inputs.new('NodeSocketImage', "Image")

bpy.utils.register_class(MyCustomNode)

if len(bpy.data.simulations) == 0:
bpy.data.simulations.new("Simulation")

sim = bpy.data.simulations[0]
sim.node_tree.nodes.new("CustomNodeType")
```

After running the script, go to the simulation editor and select the newly created simulation.

---

We might want to change `readfile.c` so that linked objects/images are only loaded,
when the socket is not connected. Otherwise it can be tricky to figure out why certain
id data blocks are still referenced by the node tree later on.
