Make bundles fully standalone (#3325)

- Bundles are fully standalone. They now include the shared loader with
  `deno_typescript`.
- Refactor of the loader in `deno_typescript` to perform module
  instantiation in a more
- Change of behaviour when an output file is not specified on the CLI.
  Previously a default name was determined and the bundle written to that
  file, now the bundle will be sent to `stdout`.
- Refactors in the TypeScript compiler to be able to support the concept
  of a request type.  This provides a cleaner abstraction and makes it
  easier to support things like single module transpiles to the userland.
- Remove a "dangerous" circular dependency between `os.ts` and `deno.ts`,
  and define `pid` and `noColor` in a better way.
- Don't bind early to `console` in `repl.ts`.
- Add an integration test for generating a bundle.
