Fix T91711: Blender 3.0 - The Rain demo scene breaks (Proxy to Override auto conversion).

Proxy conversion is a fairly particular case of liboverride creation, in
which remapping all local usages of linked data probably makes more
sense, rather than only doing so whitin the overridden 'group' of IDs.

Kernel: allow unregistering BKE callback functions

Introduce `BKE_callback_remove()`, which undoes the effect of
`BKE_callback_add()`. It also respects `funcstore->alloc` by freeing the
removed `funcstore` when needed.

This allows for shorter-lived objects in memory to unregister their
callbacks at the end of their lifespan.

`BKE_callback_global_finalize()` has been adjusted so that the
responsibility "remove a callback" is given to one function only.

Geometry Nodes: support outputting collection children as instances

This adds two new input sockets to the Collection Info node:
* `Separate Children`: When turned off, the entire collection is output as a single
collection instance (same behavior as before). When turned on, each child of
the collection is output as a separate instance (children can be objects and collections).
Toggling this input should not change the visual transforms of the output geometry.
* `Reset Children`: Only used when `Separate Children` is on. When used, the transforms
of the instances are reset to the origin. This is useful when one wants to e.g. instance
the collection children separately in the upcoming instancing node.

Part of D12478.

Geometry Nodes: new Instance on Points node

This adds a new Instance on Points node that is a replacement
for the old Point Instance node. Contrary to the old node,
it does not have a mode to instance objects or collections
directly. Instead, the node has to be used with an Object/
Collection Info to achieve the same effect.

Rotation and scale of the instances can be adjusted in the node
directly or can be controlled with a field to get some variation
between instances.

The node supports placing different instances on different points.
The user has control over which instance is placed on which point
using an Instance Index input. If that functionality is used, the
Instance Geometry has to contain multiple instances that can are
instanced separately.

Fixes T91632 by stopping the sample correlation between dimensions which was causing rendering artifacts on simple scenes.

Fix T91632: Stops the sample correlation between dimensions which was causing rendering artefacts on simple scenes.

This is done by increasing the amount of jitter the Cranley Patterson Rotation is allowed to add. Also, it uses the y dimension of the of the sample table for 1D sampling which causes further decorrelation between dimensions. As an additional measure the x and y dimensions are swapped randomly to provide further decorrelation.

Functions: fail early when multi-function throws an exception

Multi-functions are not allowed to throw exceptions that are not

Fix Alembic point cloud streaming.

Point clouds are not imported and read anymore. This was caused by an
API change in rB128eb6cbe928e58dfee1c64f340fd8d663134c26 which was not
applied to `AbcPointsReader`. It did not cause a compile error as the
base class as a default implementation for this method.

Cleanup: use override/final for derived classes.

This will help detecting missing API changes. Those keywords were added
on classes which did not already use them. Also added missing
`accepts_object_type()` on NURBS reader.
