Creating a separate interface for IncomingMessageHeaders in node/index.d.ts (#17157)

Browse Source 
* Creating a separate interface for IncomingMessageHeaders

This allows for IncomingMessage.headers types to be extensible per project. Suppose a node service expects a fixed set of headers of certain type (say string), that service can specify custom IncomingMessageHeaders with more concrete types defined.
For example

```
interface IncomingMessageHeaders {
    "host": string;
    "set-cookie": string[]
}
```

* Changing IncomingMessageHeaders defn

This definition adds undefined in addition to string and string[].
