Adds API to bake a CSG root node operation to either a static ArrayMesh or a ConcavePolygonShape3D physics collision shape. Adds menu options to the editor plugin when selecting a CSG root node to add baked sibling nodes.
The previous implementation assumed that the intersection entered or exited a
shape when it hit right on the common edge of 2 triangles. However, there is
also a case where it just "skirts" the other shape on the outside.
To fix this, we added code to check the intersection distance and if the
normals of the faces are pointed in the same direction as the intersection or
not (e.g. inner product > 0). This handles the case where the intersection
line hits the common edge of 2 triangles and skirts the other shape on the
outside.
Extended code to cover a third case.
Fixes#58637.

As many open source projects have started doing it, we're removing the
current year from the copyright notice, so that we don't need to bump
it every year.
It seems like only the first year of publication is technically
relevant for copyright notices, and even that seems to be something
that many companies stopped listing altogether (in a version controlled
codebase, the commits are a much better source of date of publication
than a hardcoded copyright statement).
We also now list Godot Engine contributors first as we're collectively
the current maintainers of the project, and we clarify that the
"exclusive" copyright of the co-founders covers the timespan before
opensourcing (their further contributions are included as part of Godot
Engine contributors).
Also fixed "cf." Frenchism - it's meant as "refer to / see".
* Previous "virtual" classes (which can't be instantiated) are not corretly named "abstract".
* Added a new "virtual" category for classes, they can't be instantiated from the editor, but can be inherited from script and extensions.
* Converted a large amount of classes from "abstract" to "virtual" where it makes sense.
Most classes that make sense have been converted. Missing:
* Physics servers
* VideoStream
* Script* classes.
which will go in a separate PR due to the complexity involved.
* Made the Basis euler orders indexed via enum.
* Node3D has a new rotation_order property to choose Euler rotation order.
* Node3D has also a rotation_mode property to choose between Euler, Quaternion and Basis
Exposing these modes as well as the order makes Godot a lot friendlier for animators, which can choose the best way to interpolate rotations.
The new *Basis* mode makes the (exposed) transform property obsolete, so it was removed (can still be accessed by code of course).
