This commit introduces the extension modes for the map UV node. The
drop-down for the extension modes is only shown if the interpolation
mode is not set to anisotropic. This is due to extension modes currently
not being supported for the anisotropic filtering.

The issue was that the parent node group was not necessarily updated already
when the tracing code ran. So use socket identifiers instead of indices to try
to find corresponding sockets between group nodes and their corresponding
node groups.
When using link-drag-search to create bundle or closure nodes, the newly created
nodes are already synced automatically. Now this automatic syncing also happens
when an empty node is first linked. If there are any sockets already, the
automatic syncing does not happen as it can be unintentional. In this case the
user can just click the sync icon in the node header to update the sockets.

This moves code used for tracing bundles and closures to a separate file. This
code is used to e.g. detect which Separate Bundle node a Combine Bundle node is
linked to. This allows providing automatic socket update operators for these
nodes. Similarly for closures.

The node uses anisotropic sampling (which is currently not supported for the
extension mode), so extension modes are only rendered in the node if any
other interpolation method, but anisotropic is selected.

This moves most of the code to deal with syncable nodes (such as
Combine/Separate Bundle) to the nodes module. Over time it might be possible to
decentralize it more.
This also changes the caching mechanism from storing a flag on the node to
storing a map on the node editor runtime data. This simplifies the code quite
significantly and also removes the need to store any of this data in DNA.
The node tree update code now always clears this cache because before it was
missing many cases, e.g. when creating links that would connect a Combine to a
Separate Bundle node.

This is a continuation of #140705. It changes more menu node options to be input
sockets. It also changes the order of the input sockets in a few cases to make
the node look a bit better.
Forward and backward compatibility is preserved.

Makes the File Output node panel similar to the Render Output node.
Instead of a dropdown, color management enum property expanded in UI.
Color management settings are now moved inside a panel.
Add/remove file subpapth buttons moved to the side of UIList.

Currently, bundles can only store socket values of Geometry Nodes. However, it
can make sense to store other kinds of data too. Specifically, this patch adds
support for storing arbitrary internal data in a bundle. This is useful when
storing e.g. the physics world when implementing a proper physics solver for
Geometry Nodes (like in #143171).
One can still see that the data exists in Geometry Nodes in the tooltip, but one
can't extract it. Built-in nodes can still read that data.
Storing built-in data in bundles can also be done as an alternative to having a
new "internal data socket" as we talked in a workshop in the past:
https://code.blender.org/2024/11/geometry-nodes-workshop-october-2024/#internal-data-sockets
A bundle still has to be copyable. Internal data is expected to use implicit
sharing. That way copying it just requires increasing the user count of the
data.

The socket name should clearly indicate the type of component being processed.
The socket names for most nodes with geometry tag are clear, with the exception of these few nodes.

This patch moves the rules that alias Image to Combined for pass names
to the context implementations. This is because this only makes sense
for contexts that deal with passes, while it wouldn't make much sense
for other possible contexts like VSE modifiers.

Use `BLI_strncpy_utf8` & `BLI_snprintf_utf8` for fixed size buffers in
DNA and screen data structures such as panels, menus & operators.
This could be considered a fix as copying a UTF8 string into a smaller
buffer without proper truncation can create an invalid UTF8 sequence.
However identifying which of these users are likely to run into would
be time consuming and not especially useful.
It allows to implement tricks based on a knowledge whether the path
ever cam through a portal or not, and even something more advanced
based on the number of portals.
The main current objective is for strokes shading: stroke shader
uses Ray Portal BSDF to place ray to the center of the stroke and
point it in the direction of the surface it is generated for. This
gives stroke a single color which matches shading of the original
object. For this usecase to work the ray bounced from the original
surface should ignore the strokes, which is now possible by using
Portal Depth input and mixing with the Transparent BSDF. It also
helps to make shading look better when there are multiple stroke
layers.
A solution of using portal depth is chosen over a single flag due
to various factors:
- Last time we've looked into it it was a bit tricky to implement
as a flag due to us running out of bits.
- It feels to be more flexible solution, even though it is a bit
hard to come up with 100% compelling setup for it.
- It needs to be slightly different from the current "Is Foo"
flags, and be more "Is Portal Descendant" or something.
An extra uint16 is added to the state to count the portal depth,
but it is only allocated for scenes that use Ray Portal BSDF.
Portal BSDF still increments Transparent bounce, as it is required
to have some "limiting" factor so that ray does not get infinitely
move to different place of the scene.

This patch improves the realism of the Fog Glow mode of the Glare node
based on the Photopic model described in:
Physically-Based Glare Effects for Digital Images" by G. Spencer, P.
Shirley, K. Zimmerman, and D. P. Greenberg.
This is a breaking change that can't be versioned, but it is worth it
for the superior realism of the new model.

This includes a new list structure type and socket shape, a node
to create lists, a node to retrieve values from lists, and a node to
retrieve the length of lists. It also implements multi-function support
so that function nodes work on lists.
There are three nodes included in this PR.
- **List** Creates a list of elements with a given size. The values
are computed with a field that can use the index as an input.
- **Get List Item** A field node that retrieves an element from a
a list at a given index. The index input is dynamic, so if the input
is a list, the output will be a list too.
- **List Length** Just gives the length of a list.
When a function node is used with multiple list inputs, the shorter
lists are repeated to extend it to the length of the longest.
The list nodes and structure type are hidden behind an experimental
feature until we can be sure they're useful for an actual use case.

Ever since [0], ReportList is not actually used in any DNA structs.
That makes sense, since reports are conceptually only necessary
at runtime. Move the definition of the struct to BKE_report.hh, and
fix a bunch of include errors where types were previously available
transitively. Besides adding some clarity, theoretically this change
could reduce compile times because of less header parsing.

If free normals already exist, the `custom_normal` attribute already
exists with a different type, so the attribute writer is not created
properly in `mesh_set_custom_normals` and the process fails. Instead,
setting tangent space custom normals should clear existing free normals.

This patch replaces the Composite node with the Group Output node as the
primary compositor output. The old node was removed and versioned. This
was done for consistency with Geometry Nodes and in preparation for more
generic use of the compositor in VSE modifiers, layered compositing, NPR
multi-stage compositing, and more.
The Group Output node relies on the node tree interface, so we now have
a default interface of a single input and a single output. For now, only
the first input is considered while the rest are ignored, just like the
Geometry Nodes design. Furthermore, the input is required to be of type
color. Warnings and errors are issues if any of those are not met, also
similar to Geometry Nodes.
This introduces a new limitation: Composite outputs can no longer exist
in node groups, since they obviously then act as their respective group
outputs.
A refactor for the compositor scheduler is needed to simplify the logic
after this change, but this will be done in a separate patch.

The issue was that the tooltip function arguments were sometimes allocated but
not freed. The solution is to handle the lifetime of the argument better. The
code now makes a copy of the argument when it's passed to a layout function. In
an idea world, one could just use something like `std::function` instead of
manual memory management, but the API does not support it yet.
This was caused by f3a1d8fad5.
