Modernized for loop style.

Show ray direction input value socket by default.

Use distance subtype for the ray length input.

Remove unnecessary noop check in interpolator.

Fixed doc string.

Move AttributeInterpolator util class to bke.

Moved the utility class to BKE_mesh_sample.
Renamed it to MeshAttributeInterpolator to make clear that it works
on mesh attributes only.

Removed the hit_index output attribute.

This output contains the looptri indices on the hit mesh, which is not
very useful.

Raycast geometry node.

The *Raycast* node intersects rays from one geometry onto another.
It computes hit points on the target mesh and returns normals, distances
and any surface attribute specified by the user.

A ray starts on each point of the input *Geometry*. Rays continue
in the *Ray Direction* until they either hit the *Target Geometry*
or reach the *Ray Length* limit. If the target is hit, the value of the
*Is Hit* attribute in the output mesh will be true. *Hit Position*,
*Hit Normal*, *Hit Distance* and *Hit Index* are the properties of the
target mesh at the intersection point. In addition, a *Target Attribute*
can be specified that is interpolated at the hit point and the result
stored in *Hit Attribute*.

Differential Revision: https://developer.blender.org/D11619

Make raycast node wider by default.

Non-zero default value for ray length.

Added a mapping mode to enable nearest point.

This would be useful in cases where attributes contain unique per-vertex
values and interpolation over triangles makes no sense. Similar to the
transfer attribute node, but raycast always looks at face corners
rather than arbitrary closes points/edges/faces of the source mesh.

Remove unused functions.

Removed the domain property of the raycast node.

Raycast always starts at point positions, there is no use case for
casting from other domains and it just complicates the node.

Rename some sockets for better clarity.

Support mesh, point cloud, and curve geometry.

Support attribute interpolation with raycast.

Support for single value input types.
