ca9cdba2df Fix: Add tooltip translation marker to disabled hints
This was overlooked, as it seems there's no way for these strings to be
translated currently. Generally it's not that clear whether `N_` or
`TIP_` should be used in this case, but `TIP_` seems more consistent.
To avoid the cost of the translation lookup when the UI text isn't
necessary, we could allow the disabled hint argument to be optional.

506d672524 Geometry Nodes: deduplicate join geometry code
The Realize Instances and Join Geometry node can share most of their code.
Until now, both nodes had their own implementations though. This patch
removes the implementation in the Join Geometry node in favor of the more
general Realize Instances implementation.

This removes an optimization for avoiding spline copies. This can be brought
back later. The realize instances code has to be rewritten to support attribute
instances anyway.

d54a08c8af Geometry Nodes: Dual Mesh Node
This node calculates the dual of the input mesh. This means that faces
get replaced with vertices and vertices with faces. In principle this
only makes sense when the mesh in manifold, but there is an option to
keep the (non-manifold) boundaries of the mesh intact.

Attributes are propagated:
 - Point domain goes to face domain and vice versa
 - Edge domain and Face corner domain gets mapped to itself
Because of the duality, when the mesh is manifold, the attributes get
mapped to themselves when applying the node twice.

Thanks to Leul Mulugeta (@Leul) for help with the
ascii diagrams in the code comments.

Note that this does not work well with some non-manifold geometry,
like an edge connected to more than 2 faces, or a vertex connected to
only two faces, while not being in the boundary. This is because there
is no good way to define the dual at some of those points. This type
of non-manifold vertices are just removed for this reason.

1757840843 Geometry Nodes: Generalized Compare Node
Replace compare floats node with a generalized compare node. The node
allows for the comparison of float, int, string, color, and vector.

The datatypes support the following operators:
Float, Int: <, >, <=, >=, ==, !=
String: ==, !=
Color: ==, !=, lighter, darker
    (using rgb_to_grayscale value as the brightness value)

Vector Supports 5 comparison modes for: ==, !=, <, >, <=, >=
Average: The average of the components of the vectors are compared.
Dot Product: The dot product of the vectors are compared.
Direction: The angle between the vectors is compared to an angle
Element-wise: The individual components of the vectors are compared.
Length: The lengths of the vectors are compared.

f8dd03d3dd Cleanup: Store instances id attribute with other attributes
Now that we can store any dynamic attribute on the instances component,
we don't need the special case for `id`, it can just be handled by the
generic attribute storage. Mostly this just allows removing a bunch
of redundant code.

I had to add a null check for `update_custom_data_pointers` because
the instances component doesn't have any pointers to inside of
custom data.

602ecbdf9a Geometry Nodes: optimize Set Position node
This implements four optimizations in the Set Position node:
* Check whether the position input is the current position and ignore
  it if it is. This results in a speedup when only the Offset input is used.
* Use multi-threading when copying to computed values to the
  position attribute. All geometry types benefit from this.
* Use devirtualization for the offset and position input. This optimizes
  the common case that they are either single values or computed
  in the fly in a span.
* Write to `Mesh->mvert` directly instead of creating a temporary span.
  This makes setting mesh vertex positions even more efficient.

In my simple benchmark I'm using a White Noise node to offset the
position of 1,000,000 vertices. The speed is `20 ms -> 4.5 ms` in the
multi-threaded case and `32 ms -> 22 ms` in the single-threaded case.

658fd8df0b Geometry Nodes: refactor multi-threading in field evaluation
Previously, there was a fixed grain size for all multi-functions. That was
not sufficient because some functions could benefit a lot from smaller
grain sizes.

This refactors adds a new `MultiFunction::call_auto` method which has the
same effect as just calling `MultiFunction::call` but additionally figures
out how to execute the specific multi-function efficiently. It determines
a good grain size and decides whether the mask indices should be shifted
or not.

Most multi-function evaluations benefit from this, but medium sized work
loads (1000 - 50000 elements) benefit from it the most. Especially when
expensive multi-functions (e.g. noise) is involved. This is because for
smaller work loads, threading is rarely used and for larger work loads
threading worked fine before already.

With this patch, multi-functions can specify execution hints, that allow
the caller to execute it most efficiently. These execution hints still
have to be added to more functions.

Some performance measurements of a field evaluation involving noise and
math nodes, ordered by the number of elements being evaluated:
```
1,000,000: 133 ms   -> 120 ms
  100,000:  30 ms   ->  18 ms
   10,000:  20 ms   ->   2.7 ms
    1,000:   4 ms   ->   0.5 ms
      100:   0.5 ms ->   0.4 ms

cf266ecaa6 Geometry Nodes: fix attribute propagation in Delete Geometry node
Previously, attribute propagation did not work correctly in when only
deleting edges and faces (but not points). Face and face corner attributes
were propagated wrongly or not at all respectively.

In order to keep the patch relatively small for the release branch,
it does not include some small optimizations. These can be done in 3.1:
* Use a `Span<int>` instead of `IndexMask` to avoid creating an
  unnecessary `Vector<int64_t>`.
* Only prepare index mappings when there are actually attributes to
  propagate.

1df8abff25 Geometry Nodes: add namespace for every file
This puts all static functions in geometry node files into a new
namespace. This allows using unity build which can improve
compile times significantly (P2578).

* The name space name is derived from the file name. That makes
  it possible to write some tooling that checks the names later on.
  The file name extension (`cc`) is added to the namespace name as
  well. This also possibly simplifies tooling but also makes it more
  obvious that this namespace is specific to a file.
* In the register function of every node, I added a namespace alias
  `namespace file_ns = blender::nodes::node_geo_*_cc;`. This avoids
  some duplication of the file name and may also simplify tooling,
  because this line is easy to detect. The name `file_ns` stands for "file
  namespace" and also indicates that this namespace corresponds to
  the current file. In the beginning I used `node_ns` but `file_ns` is more
  generic which may make it more suitable when we want to use unity
  builds outside of the nodes modules in the future.
* Some node files contain code that is actually shared between
  different nodes. For now I left that code in the `blender::nodes`
  namespace and moved it to the top of the file (couldn't move it to
  the bottom in all cases, so I just moved it to the top everywhere).
  As a separate cleanup step, this shared code should actually be
  moved to a separate file.

47276b8470 Geometry Nodes: reduce overhead when processing single values
Currently the geometry nodes evaluator always stores a field for every
type that supports it, even if it is just a single value. This results in a lot
of overhead when there are many sockets that just contain a single
value, which is often the case.

This introduces a new `ValueOrField<T>` type that is used by the geometry
nodes evaluator. Now a field will only be created when it is actually
necessary. See D13307 for more details. In extrem cases this can speed
up the evaluation 2-3x (those cases are probably never hit in practice
though, but it's good to get rid of unnecessary overhead nevertheless).

6ee2abde82 Functions: use static names for multi-functions
Previously, the function names were stored in `std::string` and were often
created dynamically (especially when the function just output a constant).
This resulted in a lot of overhead.

Now the function name is just a `const char *` that should be statically

needs a more dynamic name, it can override the `MultiFunction::debug_name`
method.

In my test file with >400,000 simple math nodes, the execution time improves from
