Currently, when `HTMLEditor` replaces text in a text node, `HTMLEditor` creates a set of `DeleteTextTransaction` and `InsertTextTransaction`. However, this has bad impact for footprint and causes the callers messy. This patch creates `ReplaceTextTransaction` instead and `HTMLEditor::ReplaceTextWithTransaction()` as its wrapper. Unfortunately, this becomes not calling `nsIEditActionListener::DidDeleteText()`, however, this is not used by mozilla-central, comm-central nor BlueGriffon. IIRC, it was not removed for some legacy addons of Thunderbird. Therefore, it must be okay to remove it. Differential Revision: https://phabricator.services.mozilla.com/D76078
