common: enable AVX512+VPCLMULQDQ for crc32c performance on x86

- Add crc32_iscsi_by16_10 in src/isa-l into candidates for ceph_crc32c
- Add hardware capability check for AVX512 instr before register
- Add NASM feature check to ensure compatibility and to enable
  AS_FEATURE_LEVEL in crc32_iscsi_by16_10.asm
