Fix embree3 build for macOS Arm (arm64)

The PR title is "fix embree3" but this actually adds a new port "embree3" which is mutually incompatible with "embree" (and thus not mergeable into the curated registry)

passes in current testing https://dev.azure.com/vcpkg/public/_build/results?buildId=127248 so I'm not sure if anything needs to be done in the current version of embree.

Note that the embree3 port was removed in #47815
