GPencil: Use correct comparison for non-bit values

ShaderNodeTree: Add flatten function to get rid of nodegroups

This makes a lot of shader node wiring code less complex.

This only add the flatten mechanism (which fixes T69672).

~~Cleanup to remove the complexity in ntree_shader_relink_displacement,
ntree_shader_bump_branches and ntree_shader_tag_nodes will be commited
separately.~~(already included)

The code is only added for shader nodes for now but could be exported to
other internal nodetree types in the future.

UI: Updated Sculpt Simplify tool icon

Fits better with the other tool icons.

Cleanup: MOD_explode: Sanitize code some more.

This happens to be a non-behavioral change, but previous code here was
*very* confusing, and only ended up generating expected results by mere
chance (since `facepa[i]` == `totpart` in case the face has no (valid)
particle, i.e. `pa == NULL`)...

Cleanup: MOD_Explode: sanitize face-without-particle case.

Systematically reset particle pointer to NULL and use it to detect
invalid particle case, instead of checking value of the face's
particle index everywhere in a confusing and prone-to-bug way
(see T70150 and previous commit).

No behavioral change expected here.

Fix T70150: Explode modifier crashes with empty vertex group.

There?s be a lot to say about that explode modifier code, for now just
follow other places in code... But the handling of 'invalid'/'unkown'
particle case is... quiet confusing to say the least.

UI: Move new sculpt mode tools to correct places in toolbar

Follows general logic, and are placed next to similar tools.

GPencil: Fix missing last point when sculpt in Multiframe

This was a mistake when fixed the problem with multiframe sculpt. I missed change the index and use active point in the check.

Mathutils: expose the swing + twist Quaternion decomposition to Python.

This decomposition is useful in rigging, and involves a math trick.
