Add examples/benchmark/dtls_bench, a DTLS throughput benchmark that completes a handshake and then measures bulk-send throughput. It supports DTLS 1.2 and 1.3, selectable cipher suites, an end-to-end mode, and a -z sink mode that discards records on the server after the handshake to isolate the sender's record-layer cost. The socket is set up with wolfSSL_set_dtls_fd_connected. Optimize the send path exercised by the benchmark: - wolfio (EmbedSendTo): cache the per-descriptor socket-type probe (getsockopt SO_TYPE) in WOLFSSL_DTLS_CTX instead of running it on every send, removing a syscall from the record send path. The cache is invalidated whenever rfd/wfd is reassigned. - internal (BuildMessage): for AEAD suites whose explicit nonce is the 8-byte record sequence number, write the sequence number directly as nonce_explicit instead of drawing it from the RNG. This covers AES-GCM (RFC 5288 sec 3), AES-CCM (RFC 6655 sec 3), SM4-GCM/CCM (RFC 8998 sec 3), and Camellia-/ARIA-GCM which inherit the RFC 5288 construction; ChaCha20 uses an implicit nonce and is excluded. A new read-only PeekSEQ() helper reads the sequence number without advancing the per-direction counter, leaving the single mandated increment to writeAeadAuthData(). Also ignore the built dtls_bench binary in .gitignore.
