This adds a new Grow/Shrink brush which is similar to the Length
brush in the old hair system.
* It's possible to switch between growing and shrinking by hold
down ctrl and/or by changing the direction enum.
* 3d brush is supported.
* Different brush falloffs are supported.
* Supports scaling curves uniformly or shrinking/extrapolating
them. Extrapolation is linear only in this patch.
* A minimum length settings helps to avoid creating zero-sized curves.

This commit re-implements the resample curve node to use the new curves
type instead of CurveEval. The largest changes come from the need to
keep track of offsets into the point attribute arrays, and the fact
that the attributes for all curves are stored in a flat array.
Another difference is that a bit more of the logic is handled by
building of the field network inputs. The idea is to let the field
evaluator handle potential optimizations while making the rest of the
code simpler.
When resampling 1 million small poly curves,the node is about 6
times faster compared to 3.1 on my hardware (500ms to 80ms).
This also adds support for Catmull Rom curve inputs.

Also replace "num" with:
- "number" when it's not used to denote the number of items.
- "digits" when digits in a string are being manipulated.

This commit adds calculation of lengths along the curve for each
evaluated point. This is used for sampling, resampling, the "curve
parameter" node, and potentially more places in the future.
This commit also includes a utility for calculation of uniform samples
in blenlib. It can find evenlyspaced samples along a sequence of points
and use linear interpolation to move data from those points to the
samples. Making the utility more general aligns better with the more
functional approach of the new curves code and makes the behavior
available elsewhere.
A "color math" header is added to allow very basic interpolation
between two colors in the `blender::math` namespace.

Previously, those methods would destruct and reconstruct
the data structure. While that was more simple in initial
implementation, it has some downsides which are not resolved:
* Already allocated memory is lost. So new memory would have
to be allocated when the data structure is refilled.
* The clearing process itself was slower because it did unnecessary
work.

Value initialization differs from default-construction in that it
also zero-initializes trivial types.

The code that eats away faces until you find input faces in
the Constrained Delaunay Triangulation goes too far and crashes
when there are no input faces. In the test case there were input
faces but they only had two vertices, so were all ignored.

In order to allow interpolation of integers with a float, add a separate
template parameter for the factor and multiplication types.
Also move some helper constexpr variables to the "base" header
(reversing the dependency to "base" -> "vector").
This also adds a distance function for scalar types, which is
helpful to allow sharing code between vectors and basic types.

This is useful to save time manually averaging many timing results.
The minimum is included because often it can be more stable than an
average, and it can help to expose calls from other contexts with lower
times that would make the average useless.

In a test file from T96282, this commit reduces the runtime of the
delete geometry node from 82 ms to 23 ms, a 3.6x improvement.
Writing to vertex groups in other cases should be faster too.
The largest improvement comes from not writing a new weight
of zero if the vertex is not in the group. This mirrors the behavior
of custom data interpolation in `layerInterp_mdeformvert`.
Other improvements come from using `set_all` for writing
output attributes and implementing that method for vertex groups.
I also implemented `materialize` methods. Though I didn't obverse
an improvement from this, I think it's best to remove virtual method
call overhead where it's simple to do so.
The test file for the delete geometry node needs to be updated.
These methods could be parallelized too, but better to do that later.

New supported features:
* 3D/spherical brush that samples a good position on the curves.
* Falloff.
The custom falloff curve mapping is not yet available in the ui because that
requires some more ui reorganization. This is better done when we have
a better understanding of what settings we need exactly.
Currently, the depth of the 3d brush is only sampled once per stroke, when
first pressing LMB. Sometimes it is expected that the depth of the brush can
change within a single brush. However, implementing that in a good way
is not straight forward and might need additional options. Therefore that
will be handled separately. Some experimentation results are in D14376.

This adds a new Add brush for the new curves object type in sculpt mode.
The brush is used to insert new curves (typically hair) on the surface object.
Supported features:
* Add single curve exactly at the cursor position when `Add Amount` is 1.
* Front faces only.
* Independent interpolate shape and interpolate length settings.
* Smooth and flat shading affects curve shape interpolation.
* Spherical and projection brush.
This also adds the `surface_triangle_index` and `surface_triangle_coordinate`
attributes. Those store information about what position on the surface each
added curve is attached to:
* `surface_triangle_index` (`int`): Index of the internal triangle that a curve
is attached to. `-1` when the curve is not attached to the surface.
* `surface_triangle_coordinate` (`float2`): First two numbers of a barycentric
coordinate that reference a specific position within the triangle.

Previously, the conversion was done manually for a fixed set of types.
Now, there is a more general utility that can be used in other contexts
(outside of geometry nodes attribute processing) as well.

This adds a prototype for the first brush that can add new curves by
painting on a surface. Note that this can only be used when the curves
object has a surface object set in the properties panel.
The brush can take minimum distance into account. This allows
distributing curves with a somewhat consistent density.

This utility is useful when using C types that own some resource in
a C++ file. It mainly helps in functions that have multiple return
statements, but also simplifies code by moving construction and
destruction closer together.

The main goal here is to add the boilerplate code to make it possible
to add the actual sculpt tools more easily. Both brush implementations
added by this patch are meant to be prototypes which will be removed

Sometimes it is useful to get the index ranges that are in an index mask.
That is because some algorithms can process index ranges more efficiently
than generic index masks.
Extracting ranges from an index mask is relatively efficient, because it is
cheap to check if a span of indices contains a contiguous range.
