std: move network code into `sys`

As per #117276, this PR moves `sys_common::net` and the `sys::pal::net` into the newly created `sys::net` module. In order to support #135141, I've moved all the current network code into a separate `connection` module, future functions like `hostname` can live in separate modules.

I'll probably do a follow-up PR and clean up some of the actual code, this is mostly just a reorganization.
