Add the necessary glue to get blake3 building for the boot loaded as well as connected to the ZFS system so it is useful. On some platforms, we create references to blake3_sse2_impl and blake3_sse41_impl ops structs to utilize SIMD. These aren't present on x86 (since we dind't ask for them), but are on aarch64 with no implementation. Since we don't want SIMD in the boot loader, have these all return 'unsupported' always. This should be fixed upstream to allow more flexibility in this selection, but for now we use this hack to not modify the sys/contrib/openzfs with difficult to maintain hacks while an upstreamable solution is found. tsoome@ did the implementation bits in sys/cddl/boot, and I did the Makefile work and the aweful blake3_impl_hack.c.
