blake2: add AVX512 accelerated implementations
* cipher/Makefile.am: Add 'blake2b-amd64-avx512.S' and
'blake2s-amd64-avx512.S'.
* cipher/blake2.c (USE_AVX512): New.
(ASM_FUNC_ABI): Setup attribute if USE_AVX2 or USE_AVX512 enabled in
addition to USE_AVX.
(BLAKE2B_CONTEXT_S, BLAKE2S_CONTEXT_S): Add 'use_avx512'.
(_gcry_blake2b_transform_amd64_avx512)
(_gcry_blake2s_transform_amd64_avx512): New.
(blake2b_transform, blake2s_transform) [USE_AVX512]: Add AVX512 path.
(blake2b_init_ctx, blake2s_init_ctx) [USE_AVX512]: Use AVX512 if HW
feature available.
* cipher/blake2b-amd64-avx512.S: New.
* cipher/blake2s-amd64-avx512.S: New.
* configure.ac: Add 'blake2b-amd64-avx512.lo' and
'blake2s-amd64-avx512.lo'.
