Part 3/3 of #109135, #110272
Switch to new node group interfaces and deprecate old DNA and API.
This completes support for panels in node drawing and in node group
interface declarations in particular.
The new node group interface DNA and RNA code has been added in parts
1 and 2 (#110885, #110952) but has not be enabled yet. This commit
completes the integration by
* enabling the new RNA API
* using the new API in UI
* read/write new interfaces from blend files
* add versioning for backward compatibility
* add forward-compatible writing code to reconstruct old interfaces
All places accessing node group interface declarations should now be
using the new API. A runtime cache has been added that allows simple
linear access to socket inputs and outputs even when a panel hierarchy
is used.
Old DNA has been deprecated and should only be accessed for versioning
(inputs/outputs renamed to inputs_legacy/outputs_legacy to catch
errors). Versioning code ensures both backward and forward
compatibility of existing files.
The API for old interfaces is removed. The new API is very similar but
is defined on the `ntree.interface` instead of the `ntree` directly.
Breaking change notifications and detailed instructions for migrating
will be added.
A python test has been added for the node group API functions. This
includes new functionality such as creating panels and moving items
between different levels.
This patch does not yet contain panel representations in the modifier
UI. This has been tested in a separate branch and will be added with a
later PR (#108565).

Customprops to IDs are supported since years through code, but were
never exposed directly in the UI of customporperties.
This commit mainly:
* Adds a new `DATA_BLOCK` type to UI customprops types.
* Exposes the existing `id_type` settings to python API.

Listing the "Blender Foundation" as copyright holder implied the Blender
Foundation holds copyright to files which may include work from many
developers.
While keeping copyright on headers makes sense for isolated libraries,
Blender's own code may be refactored or moved between files in a way
that makes the per file copyright holders less meaningful.
Copyright references to the "Blender Foundation" have been replaced with
"Blender Authors", with the exception of `./extern/` since these this
contains libraries which are more isolated, any changed to license
headers there can be handled on a case-by-case basis.
Some directories in `./intern/` have also been excluded:
- `./intern/cycles/` it's own `AUTHORS` file is planned.
- `./intern/opensubdiv/`.
An "AUTHORS" file has been added, using the chromium projects authors
file as a template.
Design task: #110784
Ref !110783.
This feature is going to be replaced with a more thorough refactoring
of the node group interface UI, which has actual node drawing support
and a new API for integration of panels into nodes.

Add support in the UI for the edit mode of curves, mesh, and point
cloud objects. It's possible to control for which mode sand object
types the asset is available with a dropdown in the node header.
To make this per-mode filtering possible, the static asset tree
cache is now unique per context mode.

No user visible changes expected, except of new experimental feature
option.
------------------------------------------------------------------------------
This introduces asset shelves as a new standard UI element for accessing
assets. Based on the current context (like the active mode and/or tool), they
can provide assets for specific workflows/tasks. As such they are more limited
in functionality than the asset browser, but a lot more efficient for certain
tasks.
The asset shelf is developed as part of the brush assets project (see #101895),
but is also meant to replace the current pose library UI.
Support for asset shelves can quite easily be added to different editor types,
the following commit will add support for the 3D View. If an editor type
supports asset shelves, add-ons can chose to register an asset shelf type for
an editor with just a few lines of Python.
It should be possible to entirely remove `UILayout.asset_view_template()` once
asset shelves are non-experimental.
Some changes are to be expected still, see #107881.

"Tool" is a more friendly word with mostly the same meaning within
Blender. Eventually it should be possible to create active tools with
node groups anyway, so the distinction isn't even helpful.
See #101778
Use instead of "'%s'" to avoid problems in the unlikely instance of
the strings containing characters that need escaping.
Also use a ternary operator instead of indexing a tuple.
Prefer the more generic exception type as it's possible exceptions
derive from this and not "Exception".
Also use the name 'ex' for exceptions instead of 'e'.
Loading a blend file with unknown regions would raise an exception.
Also remove exception where channels were skipped when the attribute
isn't found as it's no longer needed.
When pressing N-key a pie menu is shown which can toggle regions,
typically the toolbar, sidebar and the header.
This supports toggling regions without having to add a separate shortcut
for each one.
The pie menu locations selected based on the region alignment.
See #107785.
In order to avoid navigation hotkey conflicts during transform
operations, this commit implements the "Transform Navigation with Alt"
option.
This option is enabled by default and makes navigation hotkeys require
the `Alt` key during a transforming in the 3D View.

This adds support for running a set of nodes repeatedly. The number
of iterations can be controlled dynamically as an input of the repeat
zone. The repeat zone can be added in via the search or from the
Add > Utilities menu.
The main use case is to replace long repetitive node chains with a more
flexible alternative. Technically, repeat zones can also be used for
many other use cases. However, due to their serial nature, performance
is very sub-optimal when they are used to solve problems that could
be processed in parallel. Better solutions for such use cases will
be worked on separately.
Repeat zones are similar to simulation zones. The major difference is
that they have no concept of time and are always evaluated entirely in
the current frame, while in simulations only a single iteration is
evaluated per frame.
Stopping the repetition early using a dynamic condition is not yet
supported. "Break" functionality can be implemented manually using
Switch nodes in the loop for now. It's likely that this functionality
will be built into the repeat zone in the future.
For now, things are kept more simple.
Remaining Todos after this first version:
* Improve socket inspection and viewer node support. Currently, only
the first iteration is taken into account for socket inspection
and the viewer.
* Make loop evaluation more lazy. Currently, the evaluation is eager,
meaning that it evaluates some nodes even though their output may not
be required.

`use_ambient_occlusion` is a legacy property and not
connected to anything. The clip editor still write
to it for enabling the ambient occlusion renderpass.
This change will remove the legaccy option and
won't enable ambient occlusion pass anymore due
to visual and performance impact.

The "Align Rotation" operator in the UV editor was producing
unexpected results if an image was displayed with non-square aspect
ratio. This change adds the "Correct Aspect" option to the operator.
To ensure consistency between the UV unwrapping operators, the
`UV > Follow Active Quads` operator will now use 3D selection when
called from the 3D editor, and UV selection when called from the
UV editor.
This reverts commit d53862351d.
After conducting tests with artists at the studio, it was observed that
altering the Transform Modal Maps caused significant disruption due to
the heavy reliance on the "Proportional Editing" and "Automatic
Constraint" features.
Considering this, it is now deemed more beneficial to provide users
with the choice of adapting their muscle memory to the new changes.

This PR adds a new operator to run a node group on object geometry.
Only curves sculpt mode is supported for now, to simplify the design.
A new geometry node editor context to edit operator groups is also
added. This allows changing any node group, rather than only node
groups that are part of the active modifier context.
3D viewport menus are added with any geometry node group
asset in a catalog that contains the `Operator` tag. Currently Blender
must be restarted to refresh the list of available operators.
This is only the first phase of the node group operator feature.
Many more features will be added in next steps.

As suggested in #108669, the "Navigate during Transform" option has
been removed and this feature works by default.
Now if you press `G`, `R` or `S` to move, rotate or scale an object you
can also navigate in the viewport.
Note that this update modifies the default keymap.
Now pressing `Alt` is required for the following modals:
- `PROPORTIONAL_SIZE_UP`,
- `PROPORTIONAL_SIZE_DOWN`,
- `PROPORTIONAL_SIZE`,
- `AUTOIK_CHAIN_LEN_UP`,
- `AUTOIK_CHAIN_LEN_DOWN`,
- `AUTOCONSTRAIN`,
- `AUTOCONSTRAINPLANE`.

Added selection support to the Follow Active Quads operator.
Simplified code and added comments.
Also added new error codes:
* STATUS_ERR_MISSING_UV_LAYER
* STATUS_ERR_NO_FACES_SELECTED

Adds an optional list of panels to node trees. Each socket can be
assigned a panel. UI panels will be created in the future in the
modifier for these grouped sockets.
Panels are stored as a pointer array in node trees, next to socket
declarations. Each panel has a name, but it does not have to be unique.
In future a panel might also store whether it is visible by default and
similar information.
C API and RNA API are both added. Panels and their socket
assignments are accessible to users through another list in the "Group"
tab of the node editor sidebar.
Sockets in the same panel will remain together even when adding,
removing, or moving sockets or panels, renaming, etc.
A socket can be moved up or down within a panel but each panel
remains a contiguous block. Actual tree views may be created later.

Caused by 5ca65001ea (which was already patched with ae7c71ef09 and
fa5cc84a0a)
Getting the right modifier would still fail / throw errors when not done
from the modifier extra ops dropdown.
Only there, a 'modifier' attribute is set for context (via
`uiLayoutSetContextPointer` in `modifier_ops_extra_draw`).
So now check if a 'modifier' attribute is set for context (and fallback
to using the active modifier instead).
This way, polling errors in F3 search are gone and you can actually
execute the operators which are also in modifier extra ops dropdown from
elsewhere (e.g. F3 search).

Now the operator is used for both the internal & external editor,
so there is no need for the caller to call this operator only when
the preferences are set.
Add a user preference to set up a custom text editor for editing text
files with the "Edit Source" action in the UI context menu.
- An operator TEXT_OT_jump_to_file_at_point has been added.
- A custom editor can be set in the user preferences.
- A preset has been included for "Visual Studio Code".
- When the editor is not set, use Blender's internal editor.
Ref !108299.
Since ccc9eef1b9, the asset-library-reference isn't required anymore to
get the full path of an asset. So don't check for this in the `poll()`
method of the operator.
