Cleanup: remove unused MFace custom-data utilities

Remove:

- BKE_mesh_loops_to_mface_corners
- BKE_mesh_tangent_loops_to_tessdata

Fix T88605: Alembic import crashes when missing `arbGeomParams`

Add check for the `arbGeomParams` property being valid, before attempting
to access a sub-property from it.

Fluid: Optimization for FLIP neighbor search radius

Contributed by @erik85 in D11400. The idea from this patch was placed in
a more generic context: A new FOR macro has been added that loops
over the neighbors of a cell within a given radius.

Cleanup: clang format

Performance: Limit recounting during selection mode flushing.

This patch ensures that selection mode flushing updates total selection
counts internally. This reduces recounting when we are sure that the
input total selection counts were up to date.

For example for circle selection the total selection counts were
correct. But during flushing the selection could have been changed and
therefore the selection was always recounted.

This increased the performance on selected system from 6.90 FPS to 8.25
FPS during circle selection operations.

Raycast geometry node.

The //Raycast// node intersects rays from one geometry onto another.
It computes hit points on the target mesh and returns normals, distances
and any surface attribute specified by the user.

A ray starts on each point of the input //Geometry//. Rays continue
in the //Ray Direction// until they either hit the //Target Geometry//
or reach the //Ray Length// limit. If the target is hit, the value of the
//Is Hit// attribute in the output mesh will be true. //Hit Position//,
//Hit Normal//, //Hit Distance// and //Hit Index// are the properties of the
target mesh at the intersection point. In addition, a //Target Attribute//
can be specified that is interpolated at the hit point and the result
stored in //Hit Attribute//.

Cleanup: clang-tidy

Cleanup: move mesh tessellation into it's own file

This matches BMesh which also has tessellation in it's own file.

Using a separate file helps with organization when
extracting code into smaller functions.

Cleanup: replace 'unsigned in' with 'uint'

Cleanup: use standard identifier for uint64_t string formatting

Fix T89210: Box selection can fail in graphics editor

Test the intersection of segment instead of point.

Fix T89233: Incorrect attribute remove warning for curves

The curve attribute delete function didn't return whether it was
successful or not.

CMake: remove workaround for version that's no longer supported

Fix T89247: Dereference arguments to comparison function correctly

`bm_face_len_cmp` incorrectly interpreted its arguments as `BMFace *`
instead of `BMFace **`, causing an out-of-bounds read.

Fix undefs from previous commit

Fix T89234: Gpencil Separate doesn't copy settings in Stroke/Point mode

Some values were not copied from the old layer to the new one as Tint or Opacity factor.

The error affected to Strokes and Point mode

Cleanup: spelling

Cleanup: improved comment for skipping updated with zero user meshes

Noticed by @sybren D11377 review.

Cleanup: use doxy sections for rna_mesh.c

Geometry Nodes: support minimum twist normal mode

The minimum twist mode is important because it allows creating
normals without sudden changes in direction. The disadvantage
of minimum twist normals is that the normals depend on all control
points. So changing one control point can change the normals
everywhere. The computed normals do not match the existing
code exactly, although they do match quite well on non-cyclic and
on some cyclic curves. I also noticed that the existing implementation
has some fairly simple failure cases that I haven't found in the new
implementation so far.
