feat: convert to typescript (#1172)

Converts this module to typescript.

- Ecosystem modules renamed from (e.g.) `libp2p-tcp` to `@libp2p/tcp`
- Ecosystem module now have named exports
- Configuration has been updated, now pass instances of modules instead of classes:
- Some configuration keys have been renamed to make them more descriptive.  `transport` -> `transports`, `connEncryption` -> `connectionEncryption`.  In general where we pass multiple things, the key is now plural, e.g. `streamMuxer` -> `streamMuxers`, `contentRouting` -> `contentRouters`, etc.  Where we are configuring a singleton the config key is singular, e.g. `connProtector` -> `connectionProtector` etc.
- Properties of the `modules` config key have been moved to the root
- Properties of the `config` config key have been moved to the root
```js
// before
import Libp2p from 'libp2p'
import TCP from 'libp2p-tcp'

await Libp2p.create({
  modules: {
    transport: [
      TCP
    ],
  }
  config: {
    transport: {
      [TCP.tag]: {
        foo: 'bar'
      }
    },
    relay: {
      enabled: true,
      hop: {
        enabled: true,
        active: true
      }
    }
  }
})
```
```js
// after
import { createLibp2p } from 'libp2p'
import { TCP } from '@libp2p/tcp'

await createLibp2p({
  transports: [
    new TCP({ foo: 'bar' })
  ],
  relay: {
    enabled: true,
    hop: {
      enabled: true,
      active: true
    }
  }
})
```
- Use of `enabled` flag has been reduced - previously you could pass a module but disable it with config.  Now if you don't want a feature, just don't pass an implementation.   Eg:
```js
// before
await Libp2p.create({
  modules: {
    transport: [
      TCP
    ],
    pubsub: Gossipsub
  },
  config: {
    pubsub: {
      enabled: false
    }
  }
})
```
```js
// after
await createLibp2p({
  transports: [
    new TCP()
  ]
})
```
- `.multiaddrs` renamed to `.getMultiaddrs()` because it's not a property accessor, work is done by that method to calculate announce addresses, observed addresses, etc
- `/p2p/${peerId}` is now appended to all addresses returned by `.getMultiaddrs()` so they can be used opaquely (every consumer has to append the peer ID to the address to actually use it otherwise).  If you need low-level unadulterated addresses, call methods on the address manager.

BREAKING CHANGE: types are no longer hand crafted, this module is now ESM only
