feat(libp2p): add SwarmBuilder

Browse Source 
Introduce the new `libp2p::SwarmBuilder`. Users should use the new `libp2p::SwarmBuilder` instead of the now deprecated `libp2p::swarm::SwarmBuilder`. See `libp2p::SwarmBuilder` docs on how to use the new builder.

Fixes #3657.
Fixes #3563.
Fixes #3179.

Pull-Request: #4120.
