Previews: allow undo'ing datablock preview generation

Allow users to undo the effect of the "Generate Preview" operator in the
asset browser (`ED_OT_lib_id_generate_preview`). Without this, the
button is too dangerous.

Fix unreported: Flat Surface objects

Before rBf674976edd88, the flag indicating whether a curve was 2D or 3D was
ignored by Surfaces objects.

So it can be said that Surfaces objects were always 3D.

We could remove updates to 2D on Surface objects, so the behavior is
identical to what it was before.

But this would also cause the return of `data.dimensions` to be misleading,
complicate the code a bit and add a micro overhead.

So the solution here is just to init all Surface objects as 3D.

Surface objects can now be constrained to 2D with the command:
```
data.dimensions = '2D'
```

Fix T74680: Incorrect mixing in Glare node

The mixing function was designed to give correct results for Mix values of
-1, 0, and +1, but the behavior between these points was not linear. This is
unavoidable, because the function depends on both Mix and Mix^2 (by
multiplying value and mf) so they could not cancel out completely.

The new formula simply calculates the weighted sum without trying to invent
a smooth function.
Value for MixGlareOperation is now passed directly without scaling because
it is then easier to use.
Note that the previous formula performed max() twice for both input image
and the result, now there is just one max() per channel because the glare
input can't be negative.

Compositor: Allocate OIDN memory after receiving lock.

Related to {T77023}. When using many Denoise nodes the memory in OIDN
are allocated up front. A mutex could stall the process until. This
change will allocate the memory after it received the lock.

Fix T87252: File output node broken with more than 4 inputs.

In recent refactor the operator sockets were migrated from a std::list to a blender::Vector.
The way how the file output node created the sockets along mapping the sockets could
lead to storing incorrect pointers.

This patch fixes this by defining and mapping the sockets in separate loops.

Fix: File output uses incorrect resolution when first socket unused.

File output node always received the resolution from the first socket.
When that socket didn't had a link it would use a resolution of 0,0.
What lead to not saving the file at all.

This only effected Multi layer OpenEXR files.
This change would go over all the links to find the first valid
resolution.

Cleanup: remove make_quicky and enum generation utilities

- Remove `make_quicky` as on modern systems linking is the main
bottleneck, and there isn't such a gain from partial builds.

- Remove enum generator as `PyC_StringEnumItems` & `EnumPropertyItem`
are used in most places to access enums from Python, otherwise macros
are added via macros.

Fix T87157: GPencil subdivide last segment

Previously it was not possible to subdivide the last segment of a cyclic
stroke.

The fix makes sure that the correct number of new points is calculated
correctly and adds the new points to the last segment.
