Fix: properly implement the 'only append' execption case for WorkSpaces.

Add needed extra flag and utils to IDType to mark and check an ID type
as only appendable.

Note that this is only a loose user-level enforcement currently, in any
case you need to be able to link an ID to append it currently, so for
low-level code this does not really matter.

Currently only WorkSpace and Screen ID types are marked with the new
`IDTYPE_FLAGS_ONLY_APPEND` flag.

Fix T90736: Problem applying scale to curves

Curve Points of handle of type `Auto` on curves not uniformly scaled
cause the shape of the curve to be modified after applying the scale.

So change these handles to `Aligned` in these cases.

Fix T90862: Texts in Outliner can have wrong icon

In contrast to the Filebrowser, the Outliner (Blender File view) did not

Geometry Nodes: fix memory leak for multi input sockets

Functions: support optional outputs in multi-function

Sometimes not all outputs of a multi-function are required by the
caller. In those cases it would be a waste of compute resources
to calculate the unused values anyway. Now, the caller of a
multi-function can specify when a specific output is not used.
The called function can check if an output is unused and may
ignore it. Multi-functions can still computed unused outputs as
before if they don't want to check if a specific output is unused.

The multi-function procedure system has been updated to support
ignored outputs in call instructions. An ignored output just has no
variable assigned to it.

The field system has been updated to generate a multi-function
procedure where unused outputs are ignored.

Fix T87801: Eevee ambient occlusion is incorrect on M1 macMini

The issue was caused by `textureSize()` returning the size of the level 0
even when the min texture level is higher than 0.

Using a uniform to pass the correct size fixes the issue.

This issue also affected the downsampling of radiance for reflections and
refractions.

This does not affect anything other than the recusive downsampling shaders.
