TLS encryption for TCP by default

For TCP Connections, the default encryption scheme has been changed from noise to TLS for better performance. See PR for details.

Note: When making TCP connections to nodes that only support noise this will add 1 extra round trip for connection establishment. If you wish to avoid this and keep noise the default, configure your node to prefer noise over TLS like

	node, err := libp2p.New(
        ... other options
		libp2p.Security("/noise", noise.New),
		libp2p.Security("/tls/1.0.0", libp2ptls.New),
	)

Misc

• WebRTC streams now wait for a FIN_ACK before closing data channels. For more details see the specs PR: libp2p/specs#582
• Removed unused public function crypto.GenerateEKeyPair. This was used in SECIO which has been long deprecated.
• This release drops support for go1.20.
