0153e99780 Geometry Nodes: refactor logging during geometry nodes evaluation
Many ui features for geometry nodes need access to information generated
during evaluation:
* Node warnings.
* Attribute search.
* Viewer node.
* Socket inspection (not in master yet).

The way we logged the required information before had some disadvantages:
* Viewer node used a completely separate system from node warnings and
  attribute search.
* Most of the context of logged information is lost when e.g. the same node
  group is used multiple times.
* A global lock was needed every time something is logged.

This new implementation solves these problems:
* All four mentioned ui features use the same underlying logging system.
* All context information for logged values is kept intact.
* Every thread has its own local logger. The logged informatiton is combined
  in the end.

0b1050bf09 Geometry Nodes: Rename nodes for clarity between mesh and curve
Rename the mesh circle to "Mesh Circle", mesh line to "Mesh Line",
and mesh subdivide to "Mesh Subdivide". Previously they looked exactly
the same in the search menu, and the nodes themselves had the same
label. This is a "deep" rename that also renames internal defines and
function names to match the UI.

63a8b3b972 Geometry Nodes: Curve Endpoints Node
This node is quite similar to the curve to points node, but creates
points for only the start and end of each spline. This is a separate
node because the sampling from the curve to points node don't apply,
and just for ease of use.

All attributes from the curves are copied, including the data for
instancing: tangents, normals, and the derived rotations. One simple
use case is to make round caps on curves by instancinghalves of a
sphere on each end of the splines.

0521272ab3 Fix: Curve Resample Node: Copy attributes to 1 point results

586cf8b190 Nodes: Adds button to groups to change type of sockets.
The menu lists all socket types that are valid for the node tree.
Changing a socket type updates all instances of the group and keeps
existing links to the socket.
If changing the socket type leads to incorrect node connections the
links are flagged as invalid (red) and ignored but not removed. This is
so users don't lose information and can then fix resulting issues.
For example: Changing a Color socket to a Shader socket can cause an
invalid Shader-to-Color connection.

Implementation details:
The new `NODE_OT_tree_socket_change_type` operator uses the generic
`rna_node_socket_type_itemf` function to list all eligible socket types.
It uses the tree type's `valid_socket_type` callback to test for valid
types. In addition it also checks the subtype, because multiple RNA
types are registered for the same base type. The `valid_socket_type`
callback has been modified slightly to accept full socket types instead
of just the base type enum, so that custom (python) socket types can be
used by this operator.

The `nodeModifySocketType` function is now called when group nodes
encounter a socket type mismatch, instead of replacing the socket
entirely. This ensures that links are kept to/from group nodes as well
as group input/output nodes. The `nodeModifySocketType` function now
also takes a full `bNodeSocketType` instead of just the base and subtype
enum (a shortcut `nodeModifySocketTypeStatic` exists for when only
static types are used).

fd0370acc2 Geometry Nodes: Add explicit Float to Int conversion node
This patch adds a very simple node that explicitly converts a float to
an int. While this may seem redundant, it would offer 2 benefits to the
current requirement to use implicit float conversions:
 1. It makes the node tree's intent more clear and self-documenting
    (especially if changes in the future require integer inputs).
 2. It eliminates undefined behavior in current/future nodes from float
    inputs by guaranteeing that the input is an integer.

The node offers a variety of rounding techniques to make it more flexible.

9009ac2c3d Geometry Nodes: new Viewer node
This adds a viewer node similar to the one in the compositor.
The icon in the headers of nodes is removed because it served
the same purpose and is not necessary anymore.

Node outputs can be connected to the active viewer using
ctrl+shift+LMB, just like in the compositor. Right now this collides
with the shortcut used in the node wrangler addon, which will
be changed separately.

As of now, the viewed geometry is only visible in the spreadsheet.
Viewport visualization will be added separately.

There are a couple of benefits of using a viewer node compared
to the old approach with the icon in the node header:
* Better support for nodes that have more than one geometry output.
* It's more consistent with the compositor.
* If attributes become decoupled from geometry in the future,
  the viewer can have a separate input for the attribute to visualize.
* The viewer node could potentially have visualization settings.
* Allows to keep "visualization points" around by having multiple
  viewer nodes.
* Less visual clutter in node headers.

445d506ac9 Geometry Nodes: Use multithreading for the curve to mesh node
This commit optimizes the node for the case where it works on many
splines by allowing it to generate mesh data from their combinations
in parallel. By itself, this made the node around twice as fast in my
test file with a result of 20 million vertices, around 600ms instead of
1.2s before.

That isn't actually a very good result; it reveals another bottleneck,
a single threaded loop over all face corners in the mesh normal
calculation code. As a simple change that might improve performance
in some situations, this commit moves normal calculation out of this
node, so at least the work isn't wasted if the mesh is changed later
on in the node tree anyway.

ed4222258e Geometry Nodes: Add Curve Subdivision Node
This node creates splines with more control points in between the
existing control points. The point is to give the splines more
definition for further tweaking like randomization with white noise,
instead of deforming a resampled poly spline with a noise texture.

For poly splines and NURBS, the node simply interpolates new values
between the existing control points. However, for Bezier splines,
the result follows the existing evaluated shape of the curve, changing
the handle positions and handle types to make that possible.

The number of "cuts" can be controlled by an integer input, or an
attribute can be used. Both spline and point domain attributes are
supported, so the number of cuts can vary using the value from the
point at the start of each segment.

Dynamic curve attributes are interpolated to the result with linear
interpolation.

61fdc45034 Geometry Nodes: Join dynamic curve attributes in the join geometry node
This commit lets the join geometry node transfer dynamic attributes
to the result, the same way that point cloud and mesh attributes are
joined. The implementation is different though, because of an
optimization implemented for curves to avoid copying splines.

The result attribute is added with the highest priority domain (points
over splines), and the highest complexity data type. If one curve had
the attribute on the spline domain but not others, the point domain
values will be used.

Generally this is a bit lower level than I would have liked this code
to be, but should be efficient, and it's really not too complicated.
