add missing gate around Sha256_SetTransform() declaration in wolfcrypt/src/sha256.c;

remove stray definitions of XTRANSFORM*() in wolfcrypt/src/sha512.c;

restore global intel_flags in the !WC_NO_INTERNAL_FUNCTION_POINTERS paths of sha256.c and sha512.c;

disable test_wolfSSL_dtls_compare_stateless() in tests/api.c when DEBUG_VECTOR_REGISTER_ACCESS_FUZZING (it depends on a stable SHA512 hash of the in-memory struct WOLFSSL image).
