macOS: use precompiled libraries for arm64 build

Standard wiki build instructions for building Blender on macOS can now be used
on Macs with ARM processors.

This contains all libraries except for Embree and OpenImageDenoise, so Cycles
performance does not yet have full performance and features in this build. An
x86-64 build is likely to still render faster than arm64 until Embree is added.

Uses the new lib/darwin_arm64 folder. For simplicity and to keep download size
under control, both for end users and builders, we are not planning to ship
universal binaries. So this is a separate folder from lib/darwin.
