feat: Deno.core.{encode,decode}; standalone UTF-8 encoding/decoding (#4349)
This commits add two new methods to "Deno.core" namespace: "encode" and "decode".

Those methods are bound in Rust to provide a) fast b) generally available of encoding and decoding UTF-8 strings. 

Both methods are now used in "cli/js/dispatch_json.ts".
