lib/fs: convert to using internal/errors

covert lib/fs.js over to using lib/internal/errors.js
i have not addressed the cases that use errnoException(),
for reasons described in GH-12926

- throw the ERR_INVALID_CALLBACK error
  when the the callback is invalid
- replace the ['object', 'string'] with
  ['string', 'object'] in the error constructor call,
  to better match the previous err msg
  in the getOptions() function
- add error ERR_VALUE_OUT_OF_RANGE in lib/internal/errors.js,
  this error is thrown when a numeric value is out of range
- document the ERR_VALUE_OUT_OF_RANGE err in errors.md
- correct the expected args, in the error thrown in the function
  fs._toUnixTimestamp() to ['Date', 'time in seconds'] (lib/fs.js)
- update the listener error type in the fs.watchFile() function,
  from Error to TypeError (lib/fs.js)
- update errors from ERR_INVALID_OPT_VALUE to ERR_INVALID_ARG_TYPE
  in the functions fs.ReadStream() and fs.WriteStream(),
  for the cases of range errors use the new error:
  ERR_VALUE_OUT_OF_RANGE (lib/fs.js)
