All callers passed `false` for this parameter, making it more confusing
than useful. If this functionality is needed again in the future, a separate

2551cf9087 Curves: Port fillet node to the new data-block
This commit ports the fillet curves node to the new curves data-block,
and moves the fillet node implementation to the geometry module to help
separate the implementation from the node.

The changes are similar to the subdivide node or resample node. I've
resused common utilities where it makes sense, though some things like
the iteration over attributes can be generalized further. The node
is now multi-threaded per-curve and inside each curve, and some buffers
are reused per curve to avoid many allocations.

The code is more explicit now, and though there is more boilerplate to
pass around many spans, the more complex logic should be more readable.

6a1ab4747b Geometry Nodes: Copy parameters when copying a curves data-block
Previously, things like materials, symmetry, and selection options
stored on `Curves` weren't copied to the result in nodes like the
subdivide and resample nodes. Now they are, which fixes some
unexpected behavior and allows visualization of the sculpt mode
selection.

In the realize instances and join nodes the behavior is the same as
for meshes, the parameters are taken from the first (top) input.

I also refactored some functions to return a `CurvesGeometry` by-value,
which makes it the responsibility of the node to copy the parameters.
That should make the algorithms more reusable in other situations.

b876ce2a4a Geometry Nodes: new geometry attribute API
Currently, there are two attribute API. The first, defined in `BKE_attribute.h` is
accessible from RNA and C code. The second is implemented with `GeometryComponent`
and is only accessible in C++ code. The second is widely used, but only being
accessible through the `GeometrySet` API makes it awkward to use, and even impossible
for types that don't correspond directly to a geometry component like `CurvesGeometry`.

This patch adds a new attribute API, designed to replace the `GeometryComponent`
attribute API now, and to eventually replace or be the basis of the other one.

The basic idea is that there is an `AttributeAccessor` class that allows code to
interact with a set of attributes owned by some geometry. The accessor itself has
no ownership. `AttributeAccessor` is a simple type that can be passed around by
value. That makes it easy to return it from functions and to store it in containers.

For const-correctness, there is also a `MutableAttributeAccessor` that allows
changing individual and can add or remove attributes.

Currently, `AttributeAccessor` is composed of two pointers. The first is a pointer
to the owner of the attribute data. The second is a pointer to a struct with
function pointers, that is similar to a virtual function table. The functions
know how to access attributes on the owner.

The actual attribute access for geometries is still implemented with the `AttributeProvider`
pattern, which makes it easy to support different sources of attributes on a
geometry and simplifies dealing with built-in attributes.

There are different ways to get an attribute accessor for a geometry:
* `GeometryComponent.attributes()`
* `CurvesGeometry.attributes()`
* `bke::mesh_attributes(const Mesh &)`
* `bke::pointcloud_attributes(const PointCloud &)`

All of these also have a `_for_write` variant that returns a `MutabelAttributeAccessor`.

05b38ecc78 Curves: support deforming curves on surface
Curves that are attached to a surface can now follow the surface when
it is modified using shape keys or modifiers (but not when the original
surface is deformed in edit or sculpt mode).

The surface is allowed to be changed in any way that keeps uv maps
intact. So deformation is allowed, but also some topology changes like
subdivision.

The following features are added:
* A new `Deform Curves on Surface` node, which deforms curves with
  attachment information based on the surface object and uv map set
  in the properties panel.
* A new `Add Rest Position` checkbox in the shape keys panel. When checked,
  a new `rest_position` vector attribute is added to the mesh before shape
  keys and modifiers are applied. This is necessary to support proper
  deformation of the curves, but can also be used for other purposes.
* The `Add > Curve > Empty Hair` operator now sets up a simple geometry
  nodes setup that deforms the hair. It also makes sure that the rest
  position attribute is added to the surface.
* A new `Object (Attach Curves to Surface)` operator in the `Set Parent To`
  (ctrl+P) menu, which attaches existing curves to the surface and sets the
  surface object as parent.

Limitations:
* Sculpting the procedurally deformed curves will be implemented separately.
* The `Deform Curves on Surface` node is not generic and can only be used
  for one specific purpose currently. We plan to generalize this more in the
  future by adding support by exposing more inputs and/or by turning it into
  a node group.

9435ee8c65 Curves: Port subdivide node to the new data-block
This commit moves the subdivide curve node implementation to the
geometry module, changes it to work on the new curves data-block,
and adds support for Catmull Rom curves. Internally I also added
support for a curve domain selection. That isn't used, but it's
nice to have the option anyway.

Users should notice better performance as well, since we can avoid
many small allocations, and there is no conversion to and from the
old curve type.

The code uses a similar structure to the resample node (60a6fbf5b5)
and the set type node (9e393fc2f1). The resample curves node can be
restructured to be more similar to this soon though.

4593fb52cf Geometry Nodes: UV Unwrap and Pack Islands Nodes
This commit adds new Unwrap and Pack Islands nodes, with equivalent
functionality to the existing Unwrap and Pack Islands operators. The
Unwrap node uses generic boolean attributes to determine seams instead
of looking at the seam flags in the mesh geometry.

Unlike the Unwrap operator, the Unwrap node doesn't perform aspect
ratio correction, because this is trivial for the user to implement
with a Vector Math node if it is desired.

The Unwrap node implicitly performs a Pack Islands operation upon
completion, because the results may not be generally useful otherwise.
This matches the behaviour of the Unwrap operator.

The nodes use the existing Vector socket type, and do not introduce a
new 2D Vector type (see T92765).

ba1e97f1c6 Geometry Nodes: Field on Domain Node
As described in T98943, this commit adds a node that can
evaluate a field on a separate domain in a larger field context.
This is potentially useful in many cases, to avoid relying on
a separate capture attribute node, which can make it easier
to build reusable fields that don't need geometry inputs.

Internally, the node just evaluates the input field in the larger
field context and then uses the generic domain interpolation,
so the code is simple. One future optimization might be using
the input selection to only evaluate part of the input field, but
then the selection has to be interpolated as well, and that might
not always be worth it.
