Cycles: Added Embree as BVH option for CPU renders.

Note that this is turned off by default and must be enabled at build time with the CMake WITH_CYCLES_EMBREE flag.
Embree must be built as a static library with ray masking turned on, the `make deps` scripts have been updated accordingly.
There, Embree is off by default too and must be enabled with the WITH_EMBREE flag.

Using Embree allows for much faster rendering of deformation motion blur while reducing the memory footprint.

TODO: GPU implementation, deduplication of data, leveraging more of Embrees features (e.g. tessellation cache).
