feat(runtime): implement `server.requestIp` + node:http `socket.address()` (#6165)

* [server] requestIp and AnyRequestContext
Changed Request.uws_request to the new AnyRequestContext. This
allows grabbing the IP from a Request. Unfinished.

* [server] basic `requestIp` implementation

Currently using uws's requestIpAsText, which always returns a ipv6
string. We should return a `SocketAddress` object to the user instead,
which will contain the formatted address string and what type it is.
We'll have to use requestIpAsBinary and parse that ourselves.

* TypeScript docs, use `bun.String`, return `undefined` instead of `null`
if we can't get the ip.

* binary address formatting

* uws getRemoteAddress binding

* remove dead code

* working

* final touches:sparkles:

* I will abide by the results of this poll.
