Upstream some scattered Cobalt changes

These changes are found after Cobalt rebased to V8 v8.8. Most changes
are grouped into their own CLs and here are the rest.
- Replace raw printf with PrintF
- Include Starboard as a platform for some implementations
- Add some missing headers. This is probably because Cobalt does
  not compile all of V8 sources so some missing headers are only exposed
  when compiling Cobalt.
