sebastien lussier d5b66a61f2 Material Baking - Added optimized code path when baking a set of meshes with remapped UVs ...

* 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
