Aaron Kimbrell 6ca265a4d9 build(ugc): fetch and build Embree 4 for the UGC server's rays
Embree 4.4.0 (Apache-2.0) is fetched like glm and curl and built as a static
library: its own task scheduler (no TBB), triangles only, single rays, no ISPC,
SYCL, tutorials or tests; SSE2, AVX and AVX2 kernels picked at run time. Its
Debug build keeps its optimizations but not its assertions. Nothing uses it yet.

Check: a clean configure fetches embree and the build links (Linux and Windows);
the extra build time.
