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".

Malcolm Nixon 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.

Juan Linietsky 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.

Rémi Verschelde c273ddc3ee Style: Partially apply clang-tidy's `cppcoreguidelines-pro-type-member-init`
Didn't commit all the changes where it wants to initialize a struct
with `{}`. Should be reviewed in a separate PR.

Option `IgnoreArrays` enabled for now to be conservative, can be
disabled to see if it proposes more useful changes.

Also fixed manually a handful of other missing initializations / moved
some from constructors.

Style: Cleanup single-line blocks, semicolons, dead code
Remove currently unused implementation of TextureBasisU, could be re-added
later on if needed and ported.

PouleyKetchoupp d630269593 Fix contact generation with backface collision disabled
Replaced the previous implementation for backface collision handling (in
test_axis function from SAT algorithm) with much simpler logic in the
collision generation phase with face shapes, in order to get rid of
wrong contacts when backface collision is disabled.

Now it just ignores the generated collision if the contact normal is
against the face normal, with a threshold to keep edge contacts.

Added a special case for soft bodies to invert the collision instead of
ignoring it, because for now it's the best solution to avoid soft bodies
to go through concave shapes (they use small spheres). This might be
replaced with a better algorithm for soft bodies later.

PouleyKetchoupp cc39dca9f7 Rename Godot Physics classes from *SW to Godot*
Also moved MT physics server wrappers to the main servers folder, since
they don't have to be implementation specific.
