`TreeElement` isn't a trivial type anymore, so `MEM_delete()` should be
called, which calls the destructor.
AFAICS this would cause a memory leak, since the contained `unique_ptr`
is allocated but not destructed correctly - but it's not using the
guarded allocator so woudn't be reported.
Smart pointers should be the default choice for C++ owning pointers,
since they let you manage memory using RAII.
Also moved type factory methods into static class functions.
Basically this removes any C <-> C++ glue code. C++ types are accessed
directly via the public C++ APIs.
Contains some related changes like, moving functions that were
previously declared in a now removed header to a different file, whose
header is the more appropriate place (and the source file as well).
But generally I tried to avoid other changes.
The switch to how normals are kept has led to tiny differences in

Since Group Input and Output sockets happen to be of type `SOCK_CUSTOM`
[and since rBa5c59fb90ef9 custom py defined sockets are too :)] a check
introduced in rB513066e8ad6f that prevents connections for `SOCK_CUSTOM`

Now refine the check, so it specifically looks for NODE_GROUP_INPUT /
NODE_GROUP_OUTPUT, too (this keeps the intention intact to not connect
group inputs to group outputs and vice versa, but allows custom py
defined sockets to connect again) and put it in new utility function.

2-point-curves are treated separately from 3plus-point-curves (assume a
lot of the twisting reduction can be skipped, so there is a dedicated
function for single segment curves).
And while using the 3plus-point-curves function [`make_bevel_list_3D`]
would actually work in this case, the dedicated function
`make_bevel_list_segment_3D` would only consider the tilt of the second
point and would just copy over the quat to the first point as well. Dont
see a reason for this, now consider the first point's tilt as well.

The mask is only used if it's not zero. Adding the normal mask made
it not zero, but it didn't include anything else, so all custom data
layers except normals were removed. The fix is to only add normals
to the mask when it should be used.
As described in T91186, this commit moves mesh vertex normals into a
contiguous array of float vectors in a custom data layer, how face
normals are currently stored.
The main interface is documented in `BKE_mesh.h`. Vertex and face
normals are now calculated on-demand and cached, retrieved with an
"ensure" function. Since the logical state of a mesh is now "has
normals when necessary", they can be retrieved from a `const` mesh.
The goal is to use on-demand calculation for all derived data, but
leave room for eager calculation for performance purposes (modifier
evaluation is threaded, but viewport data generation is not).
**Benefits**
This moves us closer to a SoA approach rather than the current AoS
paradigm. Accessing a contiguous `float3` is much more efficient than
retrieving data from a larger struct. The memory requirements for
accessing only normals or vertex locations are smaller, and at the
cost of more memory usage for just normals, they now don't have to
be converted between float and short, which also simplifies code
In the future, the remaining items can be removed from `MVert`,
leaving only `float3`, which has similar benefits (see T93602).
Removing the combination of derived and original data makes it
conceptually simpler to only calculate normals when necessary.
This is especially important now that we have more opportunities
for temporary meshes in geometry nodes.
**Performance**
In addition to the theoretical future performance improvements by
making `MVert == float3`, I've done some basic performance testing
on this patch directly. The data is fairly rough, but it gives an idea
about where things stand generally.
- Mesh line primitive 4m Verts: 1.16x faster (36 -> 31 ms),
showing that accessing just `MVert` is now more efficient.
- Spring Splash Screen: 1.03-1.06 -> 1.06-1.11 FPS, a very slight
change that at least shows there is no regression.
- Sprite Fright Snail Smoosh: 3.30-3.40 -> 3.42-3.50 FPS, a small
but observable speedup.
- Set Position Node with Scaled Normal: 1.36x faster (53 -> 39 ms),
shows that using normals in geometry nodes is faster.
- Normal Calculation 1.6m Vert Cube: 1.19x faster (25 -> 21 ms),
shows that calculating normals is slightly faster now.
- File Size of 1.6m Vert Cube: 1.03x smaller (214.7 -> 208.4 MB),
Normals are not saved in files, which can help with large meshes.
As for memory usage, it may be slightly more in some cases, but
I didn't observe any difference in the production files I tested.
**Tests**
Some modifiers and cycles test results need to be updated with this
commit, for two reasons:
- The subdivision surface modifier is not responsible for calculating
normals anymore. In master, the modifier creates different normals
than the result of the `Mesh` normal calculation, so this is a bug
fix.
- There are small differences in the results of some modifiers that
use normals because they are not converted to and from `short`
anymore.
**Future improvements**
- Remove `ModifierTypeInfo::dependsOnNormals`. Code in each modifier
already retrieves normals if they are needed anyway.
- Copy normals as part of a better CoW system for attributes.
- Make more areas use lazy instead of eager normal calculation.
- Remove `BKE_mesh_normals_tag_dirty` in more places since that is
now the default state of a new mesh.
- Possibly apply a similar change to derived face corner normals.

Some of the message-bus macros are not safe to use in C++. This has come
up before, but no good solution was found. Now @LazyDodo, @HooglyBoogly
and I concluded this is the best duct tape "solution" for the moment.
The message-bus API should address this.
Today many users seem to think the output from

We want to refactor quite some of the Outliner code using C++, this is a
logical step to help the transition to a new architecture.
Includes plenty of fixes to make this compile without warnings, trying
not to change logic. The usual stuff (casts from `void *`, designated
initializers, compound literals, etc.).
There were a couple of function name collisions which were caused
by sharing code with the mask modifier. I just removed the dependence
on the mask modifier now. The code that I duplicated for that purpose
is only in a legacy node, so it can be expected to be removed soonish.
The fundamental limitation is that we can only have one instance
("dupli") generator at a time. Because the mesh output of a curve
object is output as an instances, the geometry set instances existed,
replacing the object as font instances. The "fix" is to reverse the
order. The behavior won't be perfect still, but at least the old
behavior will be preserved, which is really what matters for a
feature like this.
One way to take this change further would be completely disabling
regular geometry evaluation while this option is active. However,
it doesn't seem like that would actually improve the state of the code.
