This replaces the older dynamic c array macros with blender::Vector in
bmesh_polygon_edgenet. This is the only remaining use of the old array
machinery and removal of `BLI_array.h / .c` can happen immediately
afterwards.

This allows more flexibility about how we store undo data. Potentially
we wouldn't need to store everything segmented per-node if we didn't
expose the `undo::Node` struct.
Part of #118145.

Remove call to BM_elem_attrs_copy in face interpolation function.
This was copying custom-data which cleared the faces CD_BM_ELEM_PYPTR,
making the Python objects behave as if it was removed.
While the issue could also be fixed by skipping the PYPTR layer,
copying attributes such as the material & normal in a face-data
interpolation function isn't correct. In cases where this is needed,
it's better the caller handles copying attributes.
And same for the `copy_layout` function. These functions do not free any
potentially existing data in destination, but expect it to be uninitialized.
Hopefully these new names will make it more clear and avoid bugs like #122160.
A subtle error in 66da875488 mean that the existing selection
was overwritten instead of adding to the final flag on the result BMesh
element. Selection is often interpolated separately which is probably
why this mistake wasn't more observable earlier.
A subtle mistake in 66da875488 meant that existing selection
was overwritten instead of maintained in the BMesh utility functions for
copying element custom data and flags.
This pull request adds an "Active Element" node that exposes the active
vertex, edge, or face index to the geometry node tool context. The
presence of an active element is available as a boolean.
This node enables the creation of "active-to-selected" style operators.

"Own" (the adjective) cannot be used on its own. It should be combined
with something like "its own", "our own", "her own", or "the object's own".
It also isn't used separately to mean something like "separate".
Also, "its own" is correct instead of "it's own" which is a misues of the verb.
For example, creating the "position" attribute with the wrong name or type
could crash Blender when exiting edit mode. This is because some data isn't
stored as attributes in Blender, and the attribute API doesn't work very well
with BMesh.
Two parts to the solution:
- Remove builtin attributes with incorrect domains or names when
converting from BMesh to Mesh.
- Add error messages when creating builtin attributes in edit mode. It's still
possible to create name-convention attributes, because Blender should be
able to handle different types and domains for them.

* Only works on machines with a Qualcomm Snapdragon 8cx Gen3 or above.
Older generation devices are not and will not be supported due to
some driver issues
* Requires VS2022 for building.
* Uses new MSVC preprocessor for sse2neon compatibility.
* SIMD is not enabled, waiting on conversion of blenlib to C++.

This PR adds a new method to BMLog to explicitly make the intent of
searching for an entry clear and adjusts the calling code in `pbvh_bmesh`
to utilize it.

In this commit, a temporary mesh is created representing the edit mesh.
This mesh is then used in the Edit Mesh snapping system instead of the
BMesh.
By using a Mesh object for snapping, we remove a considerable amount of
code and use a more optimized version of snapping.
This simplifies the code and makes it easier to implement new features.

Along with the 4.1 libraries upgrade, we are bumping the clang-format
version from 8-12 to 17. This affects quite a few files.
If not already the case, you may consider pointing your IDE to the
clang-format binary bundled with the Blender precompiled libraries.
Except for vertex groups and a few older color types, these
are generally replaced by newer generic attribute types.
Also remove some includes of DNA_mesh_types.h, since it's
included indirectly by BKE_mesh.hh currently.
Remove most includes of this header inside other headers, to remove unnecessary
indirect includes which can have a impact on compile times. In the future we may
want more dedicated "_fwd.hh" headers, but until then, this sticks with the
solution in existing code.
Unfortunately it isn't yet possible to remove the include from `BKE_geometry_set.hh`.
Each value is now out of the global namespace, so they can be shorter
and easier to read. Most of this commit just adds the necessary casting
and namespace specification. `enum class` can be forward declared since
it has a specified size. We will make use of that in the next commit.
Use the standard "elements_num" naming, and use the "corner" name rather
than the old "loop" name: `verts_num`, `edges_num`, and `corners_num`.
This matches the existing `faces_num` field which was already renamed.

This gives better asserts in debug builds through use of Span, more
safety when name convention attributes happen to have different types
or domains, and simpler code in some cases. But the main reasoning is to
avoid relying on the specifics of CustomData more to allow us to replace
it in the future.
The version of BM_elem_attrs_copy that took a map used a reference
the version without a map didn't, which is fairly confusing.
Pass by pointer now unless this is part of a wider refactor
to move to references everywhere.
