[web-nfc] Eliminate the old NFC instance (#272)

Honry has just created a new issue for https://github.com/w3c/web-nfc:

== Eliminate the old NFC instance ==
> Each Window object where NFC is exposed has a separate NFC instance. The visibility and focus state of the Window object determines the suspended state of the associated NFC instance.

The above statement from [Handling Window visibility and focus](https://w3c.github.io/web-nfc/#handling-window-visibility-and-focus)  section still exists the old "NFC instance", should be replaced with `NFCWriter` and `NFCReader`.
