Converting multiaddrs to strings and tuples is expensive and done in many places so cache these representations when they are first requested.

These operations are surprisingly expensive:
The above is js-ipfs idling with the DHT enabled. The percentage is total CPU time. |

It turns out because `Multiaddr.encapsulate` stringifies the `Multiaddr` it's a [suprisingly expensive operation](multiformats/js-multiaddr#275 (comment)) so here we switch the order of our `Multiaddr` pipeline around so we filter undialable addresses (e.g. unsupported transports etc) before encapsulating the `PeerId` onto a `Multiaddr` we'd then just ignore.
