Cycles: Add CPU+GPU rendering support with OptiX Adds support for building multiple BVH types in order to support using both CPU and OptiX devices for rendering simultaneously. Primitive packing for Embree and OptiX is now standalone, so it only needs to be run once and can be shared between the two. Additionally, BVH building was made a device call, so that each device backend can decide how to perform the building. The multi-device for instance creates a special multi-BVH that holds references to several sub-BVHs, one for each sub-device.

Cycles: remove prefix from source code file names Remove prefix of filenames that is the same as the folder name. This used to help when #includes were using individual files, but now they are always relative to the cycles root directory and so the prefixes are redundant. For patches and branches, git merge and rebase should be able to detect the renames and move over code to the right file.
