camellia: add amd64 GFNI/AVX512 implementation
* cipher/Makefile.am: Add 'camellia-gfni-avx512-amd64.S'.
* cipher/bulkhelp.h (bulk_ocb_prepare_L_pointers_array_blk64): New.
* cipher/camellia-aesni-avx2-amd64.h: Rename internal functions from
"__camellia_???" to "FUNC_NAME(???)"; Minor changes to comments.
* cipher/camellia-gfni-avx512-amd64.S: New.
* cipher/camellia-gfni.c (USE_GFNI_AVX512): New.
(CAMELLIA_context): Add 'use_gfni_avx512'.
(_gcry_camellia_gfni_avx512_ctr_enc, _gcry_camellia_gfni_avx512_cbc_dec)
(_gcry_camellia_gfni_avx512_cfb_dec, _gcry_camellia_gfni_avx512_ocb_enc)
(_gcry_camellia_gfni_avx512_ocb_dec)
(_gcry_camellia_gfni_avx512_enc_blk64)
(_gcry_camellia_gfni_avx512_dec_blk64, avx512_burn_stack_depth): New.
(camellia_setkey): Use GFNI/AVX512 if supported by CPU.
(camellia_encrypt_blk1_64, camellia_decrypt_blk1_64): New.
(_gcry_camellia_ctr_enc, _gcry_camellia_cbc_dec, _gcry_camellia_cfb_dec)
(_gcry_camellia_ocb_crypt) [USE_GFNI_AVX512]: Add GFNI/AVX512 code path.
(_gcry_camellia_xts_crypt): Change parallel block size from 32 to 64.
(selftest_ctr_128, selftest_cbc_128, selftest_cfb_128): Increase test
block size.
* cipher/chacha20-amd64-avx512.S: Clear k-mask registers with xor.
