Adds vertex groups and basic operator support to the `GreasePencil` data
block.
Vertex groups in the `GreasePencil` ID are used as the source of truth
for vertex groups names and ordering in the UI. Individual drawings also
have vertex group lists, but they should not be modified directly by
users or the API. The main purpose of storing vertex group names in in a
drawing's `CurveGeometry` is to make it self-contained, so that vertex
weights can be associated with names without requiring the
`GreasePencil` parent data.
Vertex group operators are implemented generically for some ID types.
Grease Pencil needs its own handling in these operators. After
manipulating `vertex_group_names` the `validate_drawing_vertex_groups`
utility function should be called to ensure that drawings only contain a
true subset of the `GreasePencil` data block.
Operators for assigning/removing/selecting/deselecting vertices are also
implemented here. To avoid putting grease pencil logic into the generic
`object_deform.cc` file a number of utility functions have been added in
`BKE_grease_pencil_vgroup.hh`.

Remove transparency weight from other closure weights.
Since closure weights take transparency into account,
scaling closure colors by their weight applies alpha pre-multiplication to them,
causing dithered transparency materials to be darker than they should be.

This change makes it so the OIDN is listening to the node execution
being cancelled, allowing for a more instant user feedback on the
compositor graph changes. It is especially visible when dealing with
4k images, and using pre-filter on the guiding passes.
Similar implementation to what Cycles does.
This change covers tiles and full-frame compositors.
The GPU compositor needs extra work to have this supported.

This significantly simplifies memory management, mostly by avoiding
the need to free the memory manually. It may also improve performance,
since std::string has an inline buffer that can prevent heap
allocations and it stores the size.

Some modifiers were still using `BKE_panel_layout_panel_state_ensure` to
create open/close flag properties at runtime. Should register a RNA
property using `rna_def_modifier_panel_open_prop` instead.

Caused by 90c4e2e6ec.
We are now getting the enum item via
`RNA_property_enum_item_from_value_gettexted` (as opposed to
`RNA_property_enum_items_gettexted` prior to 90c4e2e6ec).
The former does not translate the description (whereas the later does)
which I think is just an oversight.
To resolve, now add description translation to
`RNA_property_enum_item_from_value_gettexted`.

This can potentially lead to a small speedup when the inline buffer
is very large (we don't use that anywhere), but more importantly
also quiets a wrong gcc `-Warray-bounds` warning.
This is an optional parameter for int properties, which then show up as
enum properties.
Included fix: reset ID properties' enum items when the `items` parameter is `None`.
Example usage:
```python
import rna_prop_ui
# Add a regular int property.
rna_prop_ui.rna_idprop_ui_create(D.objects['Cube'], "test", default=123, min=-3, max=500)
# Change to an enum property with items (min/max are ignored).
rna_prop_ui.rna_idprop_ui_create(D.objects['Cube'], "test", default=0, min=-10, max=10, items=[("APPLES", "Apples", ""), ("ORANGES", "Oranges", "")])
# Switch back to regular int property.
rna_prop_ui.rna_idprop_ui_create(D.objects['Cube'], "test", default=1, min=0, max=10)
```

This avoid the following error
`Unknown NIR alu instr: div 32 %17 = ineg %16`
This is a debug shader so cost isn't important.
A bug report will be done upstream.
When auto-save is slow it can be very intrusive because it freezes Blender at
unexpected times. Often people have a habit of saving frequently anyway, even
more often than auto-save would. In this case it seems unnecessary to auto-save
as well.
This patch restarts the auto-save timer when the user is saving manually to avoid
the unexpected freeze in many cases.

The output of the Color Ramp node in the GPU compositor and EEVEE is
slightly off. That's because the factor is evaluated directly at the
sampler without proper half pixel offsets to account for the sampler's
linear interpolation, which this patch adds.

Freestyle was using static PyLongObject's which relied on setting the
it's integer value directly. Replace with PyLong_FromLong(..) which
is used everywhere else.
One reference to the internal integer value needed to be kept because
Nature_Type sub-classes PyLong.
For icons that represent collapsible and collapsed content we use a
variety of icons: chevrons and closed triangles of varying
proportions. This PR makes everything use a chevron for consistency.

As discussed in the UI Module Meeting we don't have an acceptable use

This patch rewrites and optimizes the Double Edge Mask node to be orders
of magnitude faster. For a 1k complex mask, it is 650x faster, while for
a 1k simple mask, it is only 50x faster.
This improvement is attributed to the use of a new Jump Flooding
algorithm as well as multi-threading, matching the GPU implementation.
The result of the new implementation differs in that the boundaries of
the masks are now identified as the last pixels inside the mask.

The GPU implementation of the Use Alpha option of the Z Combine node
only worked if the first image is closer, since it sampled the alpha
channel from it and used it for mixing. Instead, the mix factor should
depend on the closer pixel, like the CPU implementation.
The Z Combine node switches its inputs when changing the Use Alpha
option if both Z values are equal. That's because the operations used by
the node internally use two different conditions, less than and less
than or equal. This patch fixes that by unifying it to the less than
case.
This simplifies the C++ API for making layout panels. Now it is also more similar to the Python API.
`uiLayoutPanel` is like `layout.panel` and `uiLayoutPanelProp` is like `layout.panel_prop`.
Both, `uiLayoutPanel` and `uiLayoutPanelProp`, now exist in two variants. One that takes a label
parameter and one that does not. If the label is passed in, only the panel body layout is returned.
Otherwise, the header and body are returned for more customization.

Grease pencil modifiers were using a default weight of 1.0 if the
influence vertex group is not found. Whether or not that is correct
depends on whether a vertex group is set (name not empty). In case the
name is set but the group is not found a weight of zero should be used.
This can happen in GP3 when no vertex is assigned to a vertex group,
since each drawing only has a subset of all the vertex groups.
A utility function was added to make this consistent and less error
prone.

Move WM notifiers from property setter functions to
`RNA_def_property_update` call.
This actually makes them work properly, for example setting
`bone_collection.is_solo` from Python now actually updates the armature
in the 3D Viewport. Toggling the property from the UI already worked
(for other reasons, apparently), masking this issue.
When clicking on an expandable item in the tree view, it used to
automatically expand that item. This has now been removed; clicking just
makes that item the active one.
This impacts all tree views. The authors of the following ones have been
consulted on this, and all agreed it was a good idea:
- Asset Catalogs
- Bone Collections
- Grease Pencil Layers
- Node Panels
- Light Linking (uses tree view, but just to present a flat list)
Thickness modifier ported to Grease Pencil v3.
Note: Uniform thickness range and UI step changed to better
match new thickness of blender unit.

Current method only considers first selected collection in the outliner
tree. This restricts user from selecting objects of multiple selected
collections. To fix this, first gather all the selected collections in
list with the help of `outliner_collect_selected_collections` traverse
function. Then iterate through layer collections to select base/objects
