src: throw ERR_INVALID_ARG_TYPE in C++ argument checks

- Moves THROW_AND_RETURN_IF_NOT_BUFFER and
  THROW_AND_RETURN_IF_NOT_STRING from node_crypto.cc to
  node_errors.h so it can be reused.
- Move THROW_AND_RETURN_UNLESS_BUFFER in util.h to
  node_buffer.cc and call THROW_AND_RETURN_IF_NOT_BUFFER
  there. The only other reference to THROW_AND_RETURN_UNLESS_BUFFER in
  node_i18n.cc can be safely replaced by an assertion since
  the argument will be checked in JS land.
- Migrate ERR_INVALID_ARG_TYPE errors in C++. We can move the
  checks to JS land if possible later without having to
  go semver-major.
