[issue39298] add BLAKE3 to hashlib

[Jack O'Connor]

Yeah by intrinsics I mean stuff like _mm256_add_epi32(). All of that stuff is in these vendored files:

blake3_avx2.c
blake3_avx512.c
blake3_neon.c
blake3_sse2.c
blake3_sse41.c

Also to Michał's question above, I'm not necessarily opposed to publishing something like "blake3-c" on PyPI once things stabilize. Even if we get BLAKE3 into hashlib in 3.11, PyPI modules will be useful to folks running older versions, and not everyone wants to install the Rust toolchain.
