[w3c/clipboard-apis] Add explicit language around (not) sanitizing images. (#156)

Images are only sanitized when writing to the clipboard, not when
reading them back. This is consistent with the Firefox and Safari
implementations, while Chrome also plans to match this behavior.

This is merely clarifying spec language. Before the spec was silent on
transcoding images on read, while now we make it explicit that not
transcoding should be done.

For normative changes, the following tasks have been completed:

 * [ ] Modified Web platform tests (link to pull request)

Implementation commitment:

 * [x] WebKit (matches current behavior)
 * [x] Chromium (https://chromestatus.com/feature/5629962485760000)
 * [x] Gecko (matches current behavior)
