Add SHA2 SIMD feature tests for FreeBSD
These are added: - zfs_neon_available() for arm and aarch64 - zfs_sha256_available() for arm and aarch64 - zfs_sha512_available() for aarch64 - zfs_shani_available() for x86_64 Changes: - simd_powerpc.h: change license from CDDL to BSD Tested-by: Rich Ercolani <[email protected]> Tested-by: Sebastian Gottschall <[email protected]> Reviewed-by: Brian Behlendorf <[email protected]> Signed-off-by: Tino Reichardt <[email protected]> Closes openzfs#13741
