Fix: Curve to Mesh node outputs original curve

It should only output the new mesh (and potentially instances
that are processed separately).

Fix: wrong field input deduplication with Material Selection node

Fix T91773: improve numerical stability in Curve Spiral node

Viewport Compositor: Move `rv3d->render_engine` to `DRWRenderScene`

This allows multiple instances of external render engines per viewport.
Allowing them to be combined by the compositor.

Many things needed to be ported to the draw manager since it is the only
one that can know what is inside the `DRWRenderScene` and can iterate
over all running engines.

Fix Cycles viewport flickering

Caused by a lack of synchronization between update process which sets
clear flag and the draw code checking the flag outside of a lock.

fix compiler error

Sculpt: fix drag-dot/anchored for face sets

based on the SculptCustomLayer API.

Fix color width regression in 66e24ce35bb37753b8002283a72d55639bb40239

Color buttons were drawing single icon width.

Sculpt: fix anchored/drag dot brush modes

Cleanup: remove unused SpaceImage.curtile

Cleanup: reduce Sequence size by 8 bytes

Also use int8_t for color tag.

Cleanup: isolate UDIM parameters into a struct

Passing multiple UDIM arguments into the packing function
is awkward especially since the caller may not be using UDIM.

Use an argument to store UDIM packing parameters which can be NULL,
which operates without any UDIM support.

Add a function that extracts these parameters out of the image space
allowing for multiple functions to take UDIM parameters in the future.

Mask tools: Remove mask delete tool

I have deleted the tool to delete add vertex by clicking on it. In
practise I found it not helpful, and this way it is more in line how
other elements are deleted in blender (vertices, objects etc)

Fix T91734: Crash snapping mesh if a beveled curve is present

`BKE_mesh_boundbox_get` cannot be called for objects of type Curve.

The BoundBox however does not match the object seen in the scene.
This will be dealt with in another commit.
