3f19d25018 Box Simd (#6193)
* Box Simd

* Add 256 bit version of GetAABB

* Add AABB bechmarks

* No real diff between 128 & 256, so removing 256

| Method     | Mean      | Error     | StdDev    | Ratio |
|----------- |----------:|----------:|----------:|------:|
| GetAABB    | 5.8107 ns | 0.0154 ns | 0.0137 ns |  1.00 |
| GetAABB128 | 0.4927 ns | 0.0003 ns | 0.0002 ns |  0.08 |
| GetAABB256 | 0.4332 ns | 0.0006 ns | 0.0006 ns |  0.07 |

* Add Box2Rotated.Transform Benchmark

* Results

20% faster and much smaller code. Also I don't think it inlined RotateVec

* Add Matrix3x2Helper.TransformBox() benchmark

new:

| Method    | Mean     | Error     | StdDev    | Code Size |
|---------- |---------:|----------:|----------:|----------:|
| Transform | 2.463 ns | 0.0766 ns | 0.0679 ns |     216 B |

old:
| Method    | Mean     | Error     | StdDev    | Median   | Code Size |
|---------- |---------:|----------:|----------:|---------:|----------:|
| Transform | 9.469 ns | 0.2140 ns | 0.5408 ns | 9.206 ns |     621 B |

* Fix polygon constructor

* SlimPolygonBenchmark

* use new SimdHelper for other methods

* Fix bugs

* Use new methods

* Simd SlimPolygon.ComputeAABB

* Move simd transform to physics

* Cleanup

* Remove uneccesary Unsafe.SkipInit

9cbdd1058c Use CannyFastMath & Update Some Packages (#1130)
update a bunch of packages and use JetBrains.Annotations as private asset as needed

mark some hot math methods agg inline to benefit from loop opts

use FMA for interp

use canny min/max/clamp

make Quaternion NormalizeAngle fixed time and faster

clean up YamlDotNet references

f2eb035ed8 Physics Shapes (#847)
* Adds a new IPhysicsShape object where you can define what collisions shape a PhysBody has.
AABB is now accessed through the PhysicsShape, so the BoundingBoxComponent is not required.

* Default PhysShape now copies the AABB of the BoundingBoxComponent.

* Fixed issue with serialization of PhysShapeAabbComp.

* Spatial queries now use ICollidableComponent instead of BoundingBoxComponent.
showbb now draws entities using the obsolete BoundingBoxComponent in Aqua.

* Renamed PhysShapeAabbComp to PhysShapeAabb.
Removed BoundingBoxComponent.

* Default CollidableComponent does not collide with anything now.

* Renamed ICollidable to IPhysBody.
Moved ICollidable to the Robust.Shared/Physics namespace.

* PhysShapes are now a collection of primitive shapes that contribute to the whole PhysBody.
ObjectSerializer.DataField can now deal with abstract types using YAML tags.

* Added LocalBounds property to ClickableComponent.
Added state to ClickableComponent.

* Added a Rectangle physics shape.

* ClickableComponent now actually checks that a click is inside its bounds.

* Reverted the addition of a try/catch around map loading. Any errors can propagate to the code trying to load the map again.
