Support detecting AVX512BW, AVX512VL, VAES, and VPCLMULQDQ

Add helper functions that check the AVX512BW, AVX512VL, VAES, and
VPCLMULQDQ feature bits in the CPU capability words.  Also, make sure
that OPENSSL_cpuid_setup() clears VAES and VPCLMULQDQ when they are
unsupported due to the operating system not supporting ymm registers.
