Separate the "insert nodes into group" operation into more distinct
phases. This helps to clarify what is actually happening, to avoid
redundant updates to group nodes every time a new socket is discovered,
and to make use of the topology cache to avoid the "accidentally
quadratic" alrogithms that we have slowly been removing from node
editing.
The change is motivated by the desire to use dynamic node declarations
for group nodes and group input/output nodes, where it is helpful to
avoid updating the declaration and sockets multiple times.
Use the map created for copying nodes more instead of iterating over all
nodes unnecessarily a few times. Use the map empty check instead of
a separate boolean variable. Use a utility function to retrieve a
separate buffer of selected nodes in case the nodes by id Vector
is reallocated (that part is technically a fix).
Add `bNode::index()` to allow accessing node indices directly without
manually de-referencing the runtime struct. Also adds some asserts to
make sure the access is valid and to check the nodes runtime vector.
Eagerly maintain the node's index in the tree so it can be accessed
without relying on the topology cache.

In a few places, nodes were added without updating the Identifiers and
vector. In other places nodes we removed without removing from and
rebuilding the vector. This is solved in a few ways. First I exposed
a function to rebuild the vector from scratch, and added unique ID
finding to a few places.
The changes to node group building and separating are more involved,
mostly because it was hard to see the correct behavior without some
refactoring. Now `VectorSet` is used to store nodes involved in the
operation. Some things are handled more simply with the topology
cache and by passing a span of nodes.
90ea1b7643 broke the sorting that happens as nodes are selected.
The compare function for stable sort had different requirements than
the previous implementation.
This patch adds an integer identifier to nodes that doesn't change when
the node name changes. This identifier can be used by different systems
to reference a node. This may be important to store caches and simulation
states per node, because otherwise those would always be invalidated
when a node name changes.
Additionally, this kind of identifier could make some things more efficient,
because with it an integer is enough to identify a node and one does not
have to store the node name.
I observed a 10% improvement in evaluation time in a file with an extreme
number of simple math nodes, due to reduced logging overhead-- from
0.226s to 0.205s.

This cache was never written to, only "copied" between sockets in one
case, it dates back at least a decade. It doesn't make sense to store
caches on node trees directly anyway, since they can be used in
multiple places.
With the asset identifier introduced in the previous commit, we can now
locate an asset just from its `AssetRepresentation`, without requiring
information from the asset library and the file browser storage. With
this we can remove some hacks and function parameters. A RNA/BPY
function is also affected, but I didn't remove the paramter to keep
compatibility. It's simply ignored and not required anymore, noted this
in the parameter description (noted for T102877).
`done` was only used in one place, and `is_updating` was never read.
Generally we should avoid adding this sort of temporary data to longer
lived structs.
This patch warns the user that the compositor setup is not fully
supported when an unsupported node is used. The warning is displayed as
an engine warning overlay and in the node header itself.

Some nodes, like Combine Color or the math nodes, label sockets
differently depending on the mode to be more descriptive.
`uiTemplateNodeView` now also uses this dynamic label rather than the
socket's name for labeling in the UI so the shown labels always match
the ones on the node itself.

The "Activate Same Type Next/Prev" and "Find Node" operators pan
the view to the newly selected node if it's outside of the view. This
simplifies that check and improves it in the case where the node
is only partially visible-- now it pans in while it didn't before.
The previous code was quadratic; it looped over every link for every
node. For one large node tree I tested the operator took 20ms. On the
same node tree it now takes less than 1ms.
The change replaces the current building of the "dependency list"
on every call with a use of the topology cache from 25e307d725.
Always position the nodes added with the node search at the point where
the search operator was invoked by ensuring the operator context is the
main node editor region.
This was an unintended change of rBbdb57541475f, caused by the operator
now getting the cursor position in region space. So when the operator
was called from the menu, it would get the cursor position in the
region space of the menu, which lead to an offset when adding the node
since it expected the coordinates to be in the space of the node editor.
Setting the correct operator context also fixes inconsistent transform
sensitivity depending on zoom when adding nodes via the search in the
menu which has been an issue since as far back as Blender 2.79.
Also includes a small fix for the vertical offset of nodes added by the
search which varied depending on the UI scale. Same fix as in
rB998ffcbf096e.

(Probably requires ASan for a reliable crash.)
Steps to reproduce were:
* Enter Geometry Nodes Workspace
* Press "New" button in the geometry nodes editor header
* Right-click the data-block selector -> "Mark as Asset"
* Change 3D View to Asset Browser
* Create a catalog
* Drag new Geometry Nodes asset into the catalog
* Save the file
* Press Shift+A in the geometry nodes editor
There was a general issue here with keeping catalog pointers around
during the add menu building. The way it does things, catalogs may be
reloaded in between.
Since the Current File asset library isn't loaded in a separate thread,
the use-after-free would always happen in between. For other libraries
it could still happen, but apparently didn't by chance.
