Issue Description:

With code like:

import Foundation
import FoundationNetworking

let bytes = URLSession.AsyncBytes()

Task.detached {
  let url = URL(string: "https://www.example.com")!

  await URLSession.shared.bytes(from: url)
  await URLSession.shared.data(from: url)
  await URLSession.shared.download(from: url)
}

when run via:

swiftc main.swift

gives me the following errors:

main.swift:4:24: error: type 'URLSession' has no member 'AsyncBytes'
let bytes = URLSession.AsyncBytes()
            ~~~~~~~~~~ ^~~~~~~~~~
main.swift:9:27: error: value of type 'URLSession' has no member 'bytes'
  await URLSession.shared.bytes(from: url)
        ~~~~~~~~~~~~~~~~~ ^~~~~
main.swift:10:27: error: value of type 'URLSession' has no member 'data'
  await URLSession.shared.data(from: url)
        ~~~~~~~~~~~~~~~~~ ^~~~
main.swift:11:27: error: value of type 'URLSession' has no member 'download'
  await URLSession.shared.download(from: url)
        ~~~~~~~~~~~~~~~~~ ^~~~~~~~

Is there a separate import or some other invocation (similar to import FoundationNetworking) required for non-Apple platforms to use these APIs?

IIUC these APIs aren't fully implemented in swift-corelibs-foundation.

This is insanity....

@shahmishal This is a duplicate of an issue that was transferred last year to corelibs-foundation. Can we transfer it as well?
