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 |

8d03feb84f Transform precision thing (#5451)
Just noticed it but probably doesn't affect anything really, we'll go from 64bit to 32bit after the math operations and not before.

b340e40c99 Cache physics transforms internally (#1873)
* Cache physics transforms internally

3 main points to cache them for:
1. Contact updates
2. Physics Islands solving
3. GetWorldManifold (though this is primarily for ss14).

Whenever multi-threading is done it will need adjustments to make sure no race conditions on accessing the transforms dictionary

* Also cache position and angle for GetWorldAABB

* Fix boogs

* woops
