* Add SubdAttributeInterpolation class for linear attribute interpolation.
* Dicing computes ptex UV and face ID for interpolation.
* Simplify mesh storage of subd primitive counts
* Remove kernel code for subd attribute interpolation
* Remove patch table packing and upload
The old optimization adds a fair amount of complexity to the kernel, affecting
performance even when not using the feature. It's also not that useful as it
does not work for UVs that needs special interpolation. With this simpler code
it should be easier to make it feature complete.

Scene.cpp and Geometry.cpp are large file it can be broken up into smaller easier to handle files. This change has been broken out from #105403 to make understanding the changes easier.
geometry.cpp is broken up into:
1. geometry.cpp
2. geometry_attributes.cpp
3. geometry_bvh.cpp
4. geometry_mesh.cpp
scene.h & scene.cpp is broken into:
1. scene.h
2. scene.cpp
3. devicescene.h
4. devicescene.cpp
