macOS: add Embree, OpenImageDenoise and sse2neon libraries for ARM

This required using a fork of Embree, newer LLVM version, unreleased ISPC
version and sse2neon directly from Git. Hopefully over time all the required
changes end up in official releases. For now we deviate from other platforms.

Patch based on contributions by Apple and Stefan Werner.

macOS: use sse2neon to emulate SSE instructions with Arm Neon

* WITH_CPU_SSE was renamed to WITH_CPU_SIMD, and now covers both SSE and Neon.
* For macOS sse2neon.h is included as part of the precompiled libraries.
* Adding Linux support should be possible too, but the best way to handle this
library without official releases or availability in distributions is to be
decided still.
