The viewer node in geometry node trees only supports geometry nodes.
This patch ensures that when ctrl shift clicking on a node, it will only

This is more of a first-pass refactor for the UI list template. More
improvements could be done, but that's better done separately. Main
purpose of this is to make the UI list code more manageable and ready
for the asset view template.
No functional changes for users.
* Split the huge template function into more manageable functions, with
clear names and a few structs with high coherency.
* Move runtime data management to the template code, with a free
callback called from BKE. This is UI data and should be managed at
that level.
* Replace boolean arguments with bit-flags (easily extendable and more
readable from the caller).
* Allow passing custom-data to the UI list for callbacks to access.
* Make list grip button for resizing optional.
* Put logic for generating the internal UI list identifier (stored in
.blends) into function. This is a quite important bit and a later
commit adds a related function. Good to have a clear API for this.
* Improve naming, comments, etc.
As part of further cleanups I'd like to move this to an own file.
This makes node trees with long links that cross other nodes easier to work with.
Dimmed links will be ignored by various modal operators like cut and reroute insertion.

Socket inspection helps with debugging a geometry node group.
Now, when hovering over a socket, a tooltip will appear that provides
information about the data in the socket. Note, socket inspection only
works for sockets that have been computed already. Nodes that are not
connected to an output are not computed.
Future improvements can include ui changes to make the tooltip look
more like in the original design (T85251). Furthermore, additional
information could be shown if necessary.

The backdrop image gizmo was not following the backdrop image, it
needs to be refreshed whenever the view changes. The region init
callback is executed whenever the region size changes, so that should be
a reliable place to do that.
Reported as part of T87591.
Many ui features for geometry nodes need access to information generated
during evaluation:
* Node warnings.
* Attribute search.
* Viewer node.
* Socket inspection (not in master yet).
The way we logged the required information before had some disadvantages:
* Viewer node used a completely separate system from node warnings and
attribute search.
* Most of the context of logged information is lost when e.g. the same node
group is used multiple times.
* A global lock was needed every time something is logged.
This new implementation solves these problems:
* All four mentioned ui features use the same underlying logging system.
* All context information for logged values is kept intact.
* Every thread has its own local logger. The logged informatiton is combined
in the end.

The menu lists all socket types that are valid for the node tree.
Changing a socket type updates all instances of the group and keeps
existing links to the socket.
If changing the socket type leads to incorrect node connections the
links are flagged as invalid (red) and ignored but not removed. This is
so users don't lose information and can then fix resulting issues.
For example: Changing a Color socket to a Shader socket can cause an
invalid Shader-to-Color connection.
Implementation details:
The new `NODE_OT_tree_socket_change_type` operator uses the generic
`rna_node_socket_type_itemf` function to list all eligible socket types.
It uses the tree type's `valid_socket_type` callback to test for valid
types. In addition it also checks the subtype, because multiple RNA
types are registered for the same base type. The `valid_socket_type`
callback has been modified slightly to accept full socket types instead
of just the base type enum, so that custom (python) socket types can be
used by this operator.
The `nodeModifySocketType` function is now called when group nodes
encounter a socket type mismatch, instead of replacing the socket
entirely. This ensures that links are kept to/from group nodes as well
as group input/output nodes. The `nodeModifySocketType` function now
also takes a full `bNodeSocketType` instead of just the base and subtype
enum (a shortcut `nodeModifySocketTypeStatic` exists for when only
static types are used).

This adds a viewer node similar to the one in the compositor.
The icon in the headers of nodes is removed because it served
the same purpose and is not necessary anymore.
Node outputs can be connected to the active viewer using
ctrl+shift+LMB, just like in the compositor. Right now this collides
with the shortcut used in the node wrangler addon, which will
be changed separately.
As of now, the viewed geometry is only visible in the spreadsheet.
Viewport visualization will be added separately.
There are a couple of benefits of using a viewer node compared
to the old approach with the icon in the node header:
* Better support for nodes that have more than one geometry output.
* It's more consistent with the compositor.
* If attributes become decoupled from geometry in the future,
the viewer can have a separate input for the attribute to visualize.
* The viewer node could potentially have visualization settings.
* Allows to keep "visualization points" around by having multiple
viewer nodes.
* Less visual clutter in node headers.

This changes `UI_but_func_tooltip_set` so that it allows passing a custom free function, which has two benefits:
* The caller can pass `null` to indicate that the value should not be freed.
* Arbitrary c++ data can be passed to the callback (before the struct had to be trivially destructible).
I added `uiFreeArgFunc` and used it in other places where appropriate.

Starts scrolling when dragging a node or node link and going outside the current window.
Largely copied from the VIEW2D_OT_edge_pan operator.
Edge panning operator customdata and supporting functions now in
UI_view2d.h, so they could be used by operators in other editor
libraries. The VIEW2D_OT_edge_pan operator also uses this customdata and
shared functions now. Operators properties can be used to configure
edge panning margins and speed for each use case, rather than using
hardcoded values.
The speed function for edge panning has been tweaked somewhat:
* "Speed per pixel" has been replaced with a "speed ramp" distance.
This is more intuitive and also creates an upper bound for the speed,
which can otherwise become extreme with large cursor distance.
* "Max speed" is reached at the end of the speed ramp.
* Padding the region inside and outside is applied as before, but both
values are operator properties now.
Node transform operator also supports edge panning. This requires
an offset for changes in the view2d rect, otherwise nodes are "stuck"
to the original view.
Transform operator had cursor wrapping categorically enabled, but this
gets quite confusing with the edge scrolling mechanism. A new TransInfo
option T_NO_CURSOR_WRAP has been introduced to disable this behavior.
The double negative is a bit annoying, but want to avoid affecting the
existing transform modes, so by default it should still set the
OP_IS_MODAL_GRAB_CURSOR flag (which then sets the WM_CURSOR_WRAP_XY
flag during modal execution).

This commit does two things:
* Disallows creating more than one link from one socket to a multi socket input.
* Properly count links if there happen to be more than one link between the same sockets.
The new link counting should also be more efficient asymptotically.

Since there is a special callback for assigning the name from the
search box, and the callback doesn't call an operator or something
else that would do an undo push, I think the solution is to do it
manually here.
Another option would be adding the button flag "UI_BUT_UNDO", which
isn't set by default for search buttons, but that gives us ugly names for
the undo steps, so an explicit push is better in this case.

This fixes a few "obvious" places where we do unnecessary updates.
Those special cases were added in the early days of geometry nodes
when many updates were missing and we tried to get it to work at all.
There is a fairly high risk that with this change some required updates
will be missing again. Those can be fixed when we find thme.
Some of the update issues might have been fixed by rB58818cba40794905f9323080e60884e090f2d388
and similar changes we added over time.

* Set colors for the new texture and material sockets
* Material uses the same color used for shading icons
* Texture uses a plum color desaturated enough to not be confused with Vector's violet
* Image socket adjusted to be closer to Texture sockets but darker
* Integer socket toned down in saturation to not stand out so much
(and be closer to float sockets which are gray)
Making this change now during bcon1 to gather feedback from the community,
and because Geometry Nodes needs to use the new texture/material sockets.
The sockets are not exposed in any nodes yet.
They work similar to the Object/Collection sockets, which also
just reference a data block.
This is part of D11222.
Avoids having frames with the word "Frame" on top, resulting in less visual noise.

The function applying the search used the dummy search info for when
the item doesn't exist even when there was no UI data associated with
the node at all.
A fix is to only add the search menu when there is attribute info
stored for the node. This is something I wanted to do anyway, since
it makes it look more purposeful when there are no attribute info
for a node, less like a bug.
