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.
This adds `blender::is_same_any_v` which is the almost the same as
`std::is_same_v`. The difference is that it allows for checking multiple
types at the same time.

This node is a bit special in that it uses two internal sockets
for a hack for Eevee; see rBffd5e1e6acd296a187e7af016f9d7f8a9f209f87
As a result, the `SOCK_UNAVAIL` flag is exposed to socket builder API.

Typically a node group should only have a single Group Output node.
However, currently Blender already supports having multiple group outputs,
one of which is active. This wasn't handled correctly by geometry nodes.

This looks like a copy and paste error from the original commit.
The virtual array output used the number of mesh polygons instead
of the number of edges.
If the input mesh had no materials already, the new material would
become the only material on the mesh, meaning the material was
added to all of the faces, instead of just the selected faces.
The mesh primitive nodes in geometry nodes already add an empty
slot by default, so this only affects outside geometry.
The fix is just adding an empty slot before the new slot, so the
non-selected material indices can still point to an empty slot.

Previously only the float version of the node was connected to.
This adds connection operations for vector sockets, and exposes
the "Steps" socket properly when it's selected.
Caused by capturing local variables by reference in a function that
outlives the scope it was created in. Also use a more generic function
for the first two inputs.
This should be faster because it avoids reallocating the internal
vectors when the size is known beforehand, but it may also help
a potential refactor to a different data structure (see T94193).
These pointers point to the new nodes when duplicating,
and their even used to point to "original" nodes for
"localized" trees. They're just a bad design decision
that make code confusing and buggy.
Instead, node copy functions now optionally add to a map
of old to new socket pointers. The case where the compositor
abused these pointers as "original" pointers are handled
by looking up the string node names.

Goals of this refactor:
* More unified approach to updating everything that needs to be updated
after a change in a node tree.
* The updates should happen in the correct order and quadratic or worse
algorithms should be avoided.
* Improve detection of changes to the output to avoid tagging the depsgraph
when it's not necessary.
* Move towards a more declarative style of defining nodes by having a
more centralized update procedure.
The refactor consists of two main parts:
* Node tree tagging and update refactor.
* Generally, when changes are done to a node tree, it is tagged dirty
until a global update function is called that updates everything in
the correct order.
* The tagging is more fine-grained compared to before, to allow for more
precise depsgraph update tagging.
* Depsgraph changes.
* The shading specific depsgraph node for node trees as been removed.
* Instead, there is a new `NTREE_OUTPUT` depsgrap node, which is only
tagged when the output of the node tree changed (e.g. the Group Output
or Material Output node).
* The copy-on-write relation from node trees to the data block they are
embedded in is now non-flushing. This avoids e.g. triggering a material
update after the shader node tree changed in unrelated ways. Instead
the material has a flushing relation to the new `NTREE_OUTPUT` node now.
* The depsgraph no longer reports data block changes through to cycles
through `Depsgraph.updates` when only the node tree changed in ways
that do not affect the output.
Avoiding unnecessary updates seems to work well for geometry nodes and cycles.
The situation is a bit worse when there are drivers on the node tree, but that
could potentially be improved separately in the future.
Avoiding updates in eevee and the compositor is more tricky, but also less urgent.
* Eevee updates are triggered by calling `DRW_notify_view_update` in
`ED_render_view3d_update` indirectly from `DEG_editors_update`.
* Compositor updates are triggered by `ED_node_composite_job` in `node_area_refresh`.
This is triggered by calling `ED_area_tag_refresh` in `node_area_listener`.
Removing updates always has the risk of breaking some dependency that no
one was aware of. It's not unlikely that this will happen here as well. Adding
back missing updates should be quite a bit easier than getting rid of
unnecessary updates though.

The duplicated edges were caused by 'oversubdivided' edges, i.e. edges
where some of the vertices on them are only connected to two polygons.
The fix finds these vertices and 'dissolves' them so that only one edge
is created.
For most 'normal' meshes this shouldn't occurr, or only very little, so
the performance impact of this change should be neglegible. In practice
this is also avoidable by triangulating the mesh first.

On a Ryzen 3700x, this ended up 2.5x faster than before. More
benchmarking details are included in the differential revision.
For smaller grids, all this should do is increase the
code size a bit, and add a few more if statements.

When dragging from the inputs of function nodes, other function
nodes wouldn't connect, because their socket declaration field types
weren't set correctly. Instead, they relied on code properly checking
the *node* declaration's `is_function_node()` method. However,
that increases complexity and requires passing the node instead of
just the socket in more places. Instead, set the proper field types
in the socket declaration during building.
