Releasing s2n-quic v1.77.0

Release Summary:

• feat(s2n-quic-dc-metrics): Support skipping sparse metrics emission feat(s2n-quic-dc-metrics): Support skipping sparse metrics emission #3002
• feat(s2n-quic-dc): Support querying event context on streams feat(s2n-quic-dc): Support querying event context on streams #3000
• feat(s2n-quic-dc): Support s2n-tls connection pooling; feat(s2n-quic-dc): Move server TLS builder to a Builder field; feat(s2n-quic-dc): Support configurable server stream TLS handshake timeouts feat(s2n-quic-dc): Support per-acceptor TLS configuration and connection pooling #3004
• fix(s2n-quic-dc): Avoid excluding last poll from enqueued sojourn time fix(s2n-quic-dc): Avoid excluding last poll from enqueued sojourn time #2988
• feat(s2n-quic-dc): Expose acceptor timing to application feat(s2n-quic-dc): Expose acceptor timing to application #3006
• feat(s2n-quic): Add a few frame and datagram lengths feat(s2n-quic): Add frame and datagram lengths #3007
• feat(s2n-quic-dc): Instrument connect_tls with latency/error event tracking refactor(s2n-events): Reduce generated diffs when changing metric definitions #2993
• feat(s2n-quic-dc-metrics): Expose Unit::Float in s2n-quic-dc-metrics feat(s2n-quic-dc-metrics): Expose Unit::Float in s2n-quic-dc-metrics #3011
• feat(s2n-quic-dc): Expose peer certificate chain for TLS streams feat(s2n-quic-dc): Expose peer certificate chain for TLS streams #3009
• Send MtuProbingComplete frame in Normal mode instead of MtuProbing mode. In this way, MtuProbingComplete can be coalesced with other frames which reduces the number of PADDING frames and total packets in total to be sent. fix(s2n-quic-core): move MtuProbingComplete frame sending out of MtuProbing mode #2999
