Fix T90417: font loading creates duplicate ID names

Also repair any errors in existing files.

Error from e0dd3fe5872ba37ff188e292b80b46fcf8df413c.

Cleanup: de-duplicate ID renaming utility for versioning

Icons: add license headers to utilities

Icons: update alert icon script

Missed from c549d736cff0d5013f05fb5240ef07671c5aa5ce.

Icons: resolve various issues for generating icons

- INKSCAPE_BIN environment variable was ignored by
alert_icons_update & prvicons_update.
- `make icons` wasn't regenerating alert icons.
- Updating SVG icons failed using blender built with ASAN.

adaptive_cloth: Mesh: edge flippable: no connecting edge ov1, ov2

Ensure that the edge when flipped does not already have a connecting
edge. This leads to a variety of problems like overlapping duplicate
faces or deletion of faces if no duplication is a requirement. Edge
flips should only change the orientation of the edge which is only
through connectivity change, not actually change the number of
edges/faces.

adaptive_cloth: AdaptiveMesh: flip edges: set edge size

It is important to set the edge size for all the newly created edges.

Limit the number of loops, it can easily become an infinite
loop. There should be a better solution for this but cannot think of
one as of right now.

Always check if the edge is still flippable or not. Again, this
couldn't be solved with a different flip edge algorithm where the new
edge is always added, but right now, that isn't possible.

Implement second boolean operand resampling, cleanup

Add volume grid "to_static_type" utility

Cleanup: use MEM_SAFE_FREE macro

Geometry Nodes: Select by Handle Type Node

Just like the "Select by Material" node, this node outputs a
boolean attribute for control points that have a matching handle
type. By default left and right handles are considered, but it's
possible to only check one side with the toggle in the node.

Fix: Avoid floating point error in some mesh primitive nodes

Some mesh primitives created using geometry nodes use loops to create
vertices and accumulates positions/angles in FP variables. This allows
rounding errors to accumulate and can introduce significant errors.

To minimize changes from original implementation, variables allowing
errors to accumulate are replaced by: delta * index. Affected Mesh
Primitives nodes are Line, Grid, Cylinder, Circle, Cone, and UV-Sphere.

Fix T90087: Assigning object data doesn't copy vertex groups

Assigning a mesh seems to do its own parameter copying, which
means we need to manual copy its vertex groups here, which was
just overlooked in rB3b6ee8cee708.
