* Reversed index buffers are used to handle negative scaling transforms. Since HLOD meshes will never be used with such transforms, we can get rid of these buffers and reduce memory usage.

* Forward custom primitive data info to material baking
* Added Custom Primitive Data case to material baking engine test
* Also updated broken Material Baking tests screenshots as subtle differences are now occuring on shadows... Disabled shadows from the map light source to minimize noise in future test results

* Required a source mesh with two sections with identical materials
* Occured only when created a merged mesh without baking down textures

* In this case, instead of baking each mesh material property to it's own buffer, we can write all the meshes to the same buffer as their UVs are already the final ones that do not overlap
* Memory usage is greatly reduced (in test case with ~300 materials to bake, peak is reduced by 5.5GB)
* A lot faster to process (~2x in most cases) as we are doing a single RT readback per baked material property
* We can also skip the final merge of the baked outputs, as we have a single one
Refactored the material baking module to have both code paths (single output and multi outputs) share as much code as possible

We new merge the collisions of all the instances in the ISM component, instead of a single collision instance using just the component transform.
Also exposing a utility function for getting the collision information of a list of components.
