For sake of consistencey with other node tree types, create its own cmake module.
This change helps keep `bf_nodes` focused on generic nodes files.
Texture nodes are end of life and hopefully for Blender 4.0 they can be removed.
It is not expected that these will see the updates that the other nodes are getting.
This change also helps isolate the end of life files, we may move some texture
specific node tree execution code out of `node_exec` and into a `node_texture_exec` files.

From what I can tell these are left over from Blender Internal render.
Test still pass locally, also tested a couple eevee scenes.

The crash was caused by using `modify_geometry_sets` to modify
instances, which does not generally work unfortunately.
The intended behavior was wrong anyway. In instances mode,
only top level instances should be deleted.
Also removed the old error handling because it doesn't look like it
ever worked. all_is_error remained false all the time.
Furthermore, updating it was not thread safe.

Previously operations for the math node when connecting to
outputs weren't added. It also used a different method to
check whether the link would be valid.
Along with the general changes to CPP this commit does the following
- Use static casts where possible
- Use new CPP MEM library functions instead of cast
- Use listbase macros where possible
- Declare variables where initialized

Dragging from a color socket would hit an assert in a debug build.
The node does not have a color mode currently, so use the vector mode
instead when connecting to a color socket.
Enable unity builds for `bf_nodes_shader`, gives about a 2.7x speedup
of total compile times when just building `bf_nodes_shader`.
On my machine, this equates to saving about 30 seconds.

This flag is only used a few small cases, so instead
of setting the flag for every node only set the
required flag for the nodes that require it.
Mostly the flag is used to set `ntype.flag = NODE_PREVIEW`
For nodes that should have previews by default which
is only some compositor nodes and some texture nodes.
The frame node also sets the `NODE_BACKGROUND` flag.
All other nodes were setting a flag of 0 which has no purpose.

Compare the start of the range to zero to figure out whether the
indices for the instances to keep starts at zero. Also rename the
selection argument, since it made it seem like the selected indices
should be removed rather than kept.
Calculates the angle in radians between two faces that meet at an edge.
0 to PI in either direction with flat being 0 and folded over on itself PI.
If there are not 2 faces on the edge, the angle will be 0.
For valid edges, the angle is the same as the 'edge angle' overlay.
For the Face and Point domain, the node uses simple interpolation to calculate a value.

Exposes compare operations via rna emums.
This uses the rna enum to build the search list using
named operations linked to socket A.
This also weights the Math Node comparison operations lower
for geometry node trees.

As @hooglyboogly suggested in D13680, this patch adds weighting
to the search results. Dragging from a vector/rgba socket weights
the Vector Math node higher than a float Math node, and vice versa.

Ever since the instance domain was added, this was exposed, it just
didn't do anything. This patch implements the instances domain in the
delete and separate geometry nodes, where it acts on the top-level
instances.
We act on a mutable instances input, with the idea that eventually
copy on write attribute layers will make this less expensive. It also
allows us to keep the instance references in place and to do less
work in some situations.

This function node creates a running total of a given Vector, Float, or
Int field.
Inputs:
- Value: The field to be accumulated
- Group Index: The values of this input are used to aggregate the input
into separate 'bins', creating multiple accumulations.
Outputs:
- Leading and Trailing: Returns the running totals starting
at either the first value of each accumulations or 0 respectively.
- Total: Returns the total accumulation at all positions of the field.
There's currently plenty of duplicate work happening when multiple outputs
are used that could be optimized by a future refactor to field inputs.

Unity build saves 5 seconds off the total build time when compiling `bf_nodes_function`.
Total build times went from 25s to 20s (20% reduction),
tested with ninja on linux running i5 8250U.
Using the output declarations is incorrect because there is a
declaration for each type. Instead loop over the names directly,
since it will make it easier to add an integer mode that only
supports some of the outputs.
