embree: Fix Linux ARM64 build with -flax-vector-conversions

This is a change done upstream in the `devel3` branch for 3.13.6:
82ca6b5ccb

They also seem to define it for macOS, but for us it breaks the build...
¯\_(ツ)_/¯

Also change wrong use of CPPFLAGS (pre-processor) where CXXFLAGS (C++)
makes more sense.
