Cleanup: sort include dirs in CMakeLists.txt

Sort include dirs in just one file, not a big change
(`source/blender/editors/armature/CMakeLists.txt`).

No functional changes.

Geometry Nodes: remove some unnecessary updates

This fixes a few "obvious" places where we do unnecessary updates.
Those special cases were added in the early days of geometry nodes
when many updates were missing and we tried to get it to work at all.
There is a fairly high risk that with this change some required updates
will be missing again. Those can be fixed when we find thme.
Some of the update issues might have been fixed by rB58818cba40794905f9323080e60884e090f2d388
and similar changes we added over time.

Animation: Pose sliding tools improvements

Improve the "In Betweens" tools:
- Push Pose from Rest Pose
- Relax Pose to Rest Pose
- Push Pose from Breakdown
- Relax Pose to Breakdown
- Pose Breakdowner

These all now use the same new sliding tool:
- Actual visual indication of the blending/pushing percentage applied.
- Mouse wrapping to allow for extrapolation without having to worry
about the initial placement of the mouse. This also means these tools
are actually usable when chosen from the menu.
- Precision mode by holding {key Shift}.
- Snapping to 10% increments by holding {key Ctrl}.
- Overshoot protection; by default the tool doesn't allow overshoot
(lower than 0% or higher than 100%), and it can be enabled by pressing
{key E}.
- Bones are hidden while sliding, so the pose itself can be seen more
clearly. This can be toggled by pressing {key H} while using the tool.

Fix sculpt neighbor iterator not taking visibility into account

Sculpting tools are designed to ignore hidden geometry and behave like
hidden geometry does not exist.
When getting the neighbors of a vertex, now this takes into account
hidden geometry to avoid returing neighbors which connected edge is not
visible. This should make corner cases of a lot of tools work properly,
especially when working in low poly meshes when is common to have a
single face loop hidden.

Fix T87929: Cycles, missing update when visibility is modified

This issue originates from a missing BVH packing for visibility data
when it is modified.

To fix this, this adds update flags to the managers to carry the
modified visibility information from the Objects' modified flag to the
GeometryManager.

Another set of flags is added to determine which data need to be packed:
geometry, vertices, or visibility. Those flags are then used when
packing the primivites.

USD Export: spurious error message.

Calling BLI_dir_create_recursive() with a path that has a
trailing slash generates an error message that the directory
couldn't be created, even though the creation is successful.
The error message appears to be spurious, but I changed the
code to use a path with no trailing slash, to avoid this.

Fix Sculpt tools showing the cursor of the previous active brush

When using a tool that is not a brush, the previously used brush
preset will still be active in the tool settings, so the cursor will
draw its custom reviews.
This checks if the current active tool is a brush before drawing its
previews. If it is not a brush tools, it draws a default white cursor.

Functions: Expose set_all method for generic virtual arrays

This is very similar to rB5613c61275fe6 and rB0061150e4c90d, basically
just exposing a `VMutableArray` method to its generic counterpart. This
is quite important for curve point attributes to avoid a lookup for
every point when there are multiple splines.
