Fix error in Cycles geometry update tagging after pointcloud addition

Thanks to Christophe Hery for spotting this.

Fix T94142, T94182: Cycles metal broken after pointcloud changes

Missing ccl_private form an older patch.

Fix T94137: GPencil: Eraser does not erase first point

The eraser checks the current, previous and next point (and sets pc0,
pc1 & pc2 corresponding to that for futher occlusion/brush/clipping
checks). For the very first point, it sets pc0 to pc1 [which makes sense,
there is no previous point, so we should assume the previous segment is
"visible" as soon as the first point is], but does so *before* pc1 is
even calculated. This makes following occlusion/brush/clipping checks
work with zero values [which leads to no earsing in most cases].

Now *first* calculate pc1, *then* set pc0 to pc1.

Outliner ID Remap Users: hide ID type from the UI

The correct type should be set by invoke already, changing it to a non-
matching type (e.g. trying to remap Mesh users with a Camera block) does
not really make sense afaict, reason being that we would be presented
with the "Invalid old/new ID pair" message in such case anyways (code
checks GS(old_id->name) == GS(new_id->name)).

This alone wouldnt be a pressing issue, but since doing this with an
object ID type crashes atm., it seems to make sense to clean this up now
(of course the crash should be looked into, but this is for a separate
patch -- if that is solved, we could also think about adding the "Remap
Users" entry back in the context menu for objects as well [which was
removed in rB17bd5c9d4b1e for some reason]).

Fix (unreported): missed running versioning code in some files

The versioning code was accidentally put not at the very bottom.
That lead to a situation where it wasn't run on some files that happened
to be within a specific short time frame.

Since the versioning code is idempotent, it can just run again on existing
files. Therefore, this commit just moves it back to the bottom so that it
is executed on all files again.

Fix T94166: set handle position node crashed after refactor

This was an oversight in rB8e2c9f2dd3118bfdb69ccf0ab2b9f968a854aae4.

GPU: Sort SSBOs In Shader Interface.

SSBOs weren't sorted, but other types were. This was an
oversight when SSBOs were introduced (GPU compute pipeline).

Issue identified by @fclem.

Cleanup: Silenced unused var warnings.

UI: move "undo history" from a custom popup to a menu type

This lets the undo history expand as a regular sub-menu
instead of being a popup.

Also disable the active undo step menu item as this is a no-op.

Cleanup: spelling in comments

Cleanup: use more common naming suffix for item callbacks

UI: Correct "QuickTime" Spelling

Change the spelling of the QuickTime output video container item from
"Quicktime" to "QuickTime"

Cleanup: Simplify logic in set material node

Geometry Nodes: Support point clouds in the set material node

Now that point clouds can be rendered with cycles, it makes sense
to allow assigning a material to them. Note that like volumes, they
only support a single material though.

Cycles: pointcloud rendering

This add support for rendering of the point cloud object in Blender, as a native
geometry type in Cycles that is more memory and time efficient than instancing
sphere meshes. This can be useful for rendering sand, water splashes, particles,
motion graphics, etc.

Points are currently always rendered as spheres, with backface culling. More
shapes are likely to be added later, but this is the most important one and can
be customized with shaders.

For CPU rendering the Embree primitive is used, for GPU there is our own
intersection code. Motion blur is suppored. Volumes inside points are not
currently supported.

Implemented with help from:
* K�vin Dietrich: Alembic procedural integration
* Patrick Mourse: OptiX integration
* Josh Whelchel: update for cycles-x changes

Revert "Cycles-X: Add hysteresis to resolution divider algorithm"

This reverts commit d8b42751625c915113b64f5a2d9c72f19f009fee. It causes reduced
viewport render resolution. Revert for now until I have time to look into this
more closely.

Cleanup: Move curve.c to C++

I need this for a refactor I'm looking into for bounding boxes.
It may be helpful in the future when using `CurveEval` in more places.

LibOverride: Further improve creation/resync pre-process speed.

Fully get rid of `BKE_collection_object_find` in
`lib_override_group_tag_data_object_to_collection_init`, even if only
used a few times this function was still noticeable in profiling data.

Now instead loop over collections' objects to build required
object-to-collections mapping.

Adds an extra 5-10% speed-up compared to previous commit rB0624fad0f3ff.
