Attachment: Bug 1922723 - Enable `contenteditable=plaintext-only` only in the Nightly channel r=m_kato!,#dom-core

Let's enable contenteditable=plaintext-only only in the Nightly channel to
collect bug reports from the testers.

Depends on D224578

Once this lands, it should be documented at https://developer.mozilla.org/en-US/docs/Mozilla/Firefox/Experimental_features and the browser compat data should be updated and reference this bug. Pref is dom.element.contenteditable.plaintext-only.enabled.

:masayuki could you consider nominating this for a release note? (Process info)
We could include it in the nightly only release notes.

Release Note Request (optional, but appreciated)
[Why is this notable]: A new feature of contenteditable which only Firefox has not supported yet.
[Affects Firefox for Android]: Yes.
[Suggested wording]: Basic features of contenteditable="plaintext-only" are now supported and enable only in the Nightly channel. However, we still use <br> elements for line breaks in contenteditable="plaintext-only" even when white-space is pre, pre-line or pre-wrap. Therefore, textContent of editing host returns one line text even there are multiple lines in it. This issue is handled in bug 1922724.
