Add sync version of std/io readLines

It would be useful to provide a function that can read a line of input from stdin that has a simple interface. It would probably good to support both async and sync versions, something like

const name: string = await Deno.readLine('What is your name? ');
const age: string = Deno.readLineSync('What is your age? ');

I think readLine might be too close to the file functions, so maybe something like getInput or ttyReadLine

It’s now possible to do that using readLines from std/io/bufio.ts

import { readLines } from "https://deno.land/std@v0.35.0/io/bufio.ts";

async function main() {
   for await (const line of readLines(Deno.stdin)) {
      console.log("read line", line);
  }
}

console.log("reading lines from stdin");
main();

$ deno index.ts
Compile file:///Users/biwanczuk/dev/deno/index.ts
reading lines from stdin
asdf
read line asdf
qwer
read line qwer
tryu
read line tryu

I believe this could be implemented in pure TS with Deno.stdin, so we should probably put this in deno_std
