2290f3b6a4 Fix CCD in case of multiple supports in motion direction 
For example, an axis-aligned box under the influence of gravity landing
on a horizontal triangle could previously tunnel, because only one of
the supports of the box was considered to be the candidate point that
would collide first. Now all supports are considered as candidates.

Also fix CCD always pushing the fast body into the other body, which
works well for convex shapes but not for trimesh/concave shapes.

One Copyright Update to rule them all 
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".

37e4f8befa Micro-optimizations of the GodotConvexPolygonShape3D::get_support function. Specifically this uses pointer-array-dereference rather than LocalVector<T> dereference as this performs range-checking on known-good indexes. 
Added more comments. Changed loops back to classic for-iteration style.

220e8a0390 Modified the collision_sphere_capsule function to only test the one "correct" axis which corresponds to the correct collision normal. 
Added logically identical fix to the capsule/capsule collision, and verified it now produces correct collision points and normals.

Added analytic_sphere_collision helper function which reports the A and B points directly without using SAT.

Modified _collision_sphere_sphere, _collision_sphere_capsule, and _collision_capsule_capsule to use the new analytic_sphere_collision.

Fix white-space issue

Additional code formatting fixes.

Updated new analytic_sphere_collision to correctly handle null collector callback.

length zero in case the capsule degenerates to a sphere or circle.

71d2e38cb5 Optimize Convex Collision 
Implements the Gauss Mapping optimization to SAT convex collision test.

* Described [here](https://ubm-twvideo01.s3.amazonaws.com/o1/vault/gdc2013/slides/822403Gregorius_Dirk_TheSeparatingAxisTest.pdf) by Dirk Gregorius.
* Requires adding of face information to edges in MeshData
* Took the chance to convert MeshData to LocalVector for performance.
