feat: prioritize noise over secio (#3216)

This would be good to land in 0.49 as we're planning to remove support for SECIO in 0.50. 

- When dialing js-ipfs >=0.47, or go-ipfs >=0.5 nodes, there will be no latency hit as we can start Noise immediately.
- Incoming dials for ipfs <0.49 and >0=0.47, will take a round trip hit when connecting as they'll fail to negotiate Secio and fallback to Noise
