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.

c7255388e1 Remove ThreadWorkPool, replace by WorkerThreadPool 
The former needs to be allocated once per usage. The later is shared for all threads, which is more efficient.
It can also be better debugged.

746dddc067 Replace most uses of Map by HashMap 
* Map is unnecessary and inefficient in almost every case.
* Replaced by the new HashMap.
* Renamed Map to RBMap and Set to RBSet for cases that still make sense
  (order matters) but use is discouraged.

There were very few cases where replacing by HashMap was undesired because
keeping the key order was intended.
I tried to keep those (as RBMap) as much as possible, but might have missed
some. Review appreciated!

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.

109d08c84a Add protective checks for invalid handle use in BVH 
Adds DEV_ASSERTS that will halt at runtime if the BVH is misused with invalid IDs, and adds ERR_FAIL macros to prevent calling with invalid IDs.

Any such misuse is a bug in the physics, but this should flag any errors quickly.

8b547331be Create GDExtension clases for PhysicsServer3D 
* Allows creating a GDExtension based 3D Physics Server (for Bullet, PhysX, etc. support)
* Some changes on native struct binding for PhysicsServer

This allows a 3D Physics server created entirely from GDExtension. Once it works, the idea is to port the 2D one to it.

30a608b7b9 Fix rigid body ray cast CCD in 2D and 3D Godot Physics 
For 2D:
Raycast CCD now works the same as in 3D, it changes the body's velocity
to place it at the impact position instead of generating a contact point
that causes a wrong push back.

For both 2D and 3D:
The raycast CCD process reads and modifies body velocities, so it needs
to be moved to pre_solve() instead of setup() to be processed linearly
on the main thread, otherwise multithreading can cause some CCD results
to be randomly lost when multiple collisions occur.

940f3fde5c Improve RigidDynamicBody force and torque API 
Makes the API for forces and impulses more flexible, easier to
understand and harmonized between 2D and 3D.

Rigid bodies now have 3 sets of methods for forces and impulses:
-apply_impulse() for impulses (one-shot and time independent)
-apply_force() for forces (time dependent) applied for the current step
-add_constant_force() for forces that keeps being applied each step

Also updated the documentation to clarify the different methods and
parameters in rigid body nodes, body direct state and physics servers.
