fix!: remove @libp2p/components (#192)

`@libp2p/components` is a choke-point for our dependency graph as it depends on every interface, meaning when one interface revs a major
`@libp2p/components` major has to change too which means every module depending on it also needs a major.

Switch instead to constructor injection of simple objects that let modules declare their dependencies on interfaces directly instead of
indirectly via `@libp2p/components`

Refs libp2p/js-libp2p-components#6

BREAKING CHANGE: modules no longer implement `Initializable` instead switching to constructor injection
