feat: Implement LatestContentProvider for WebView recovery (#22774)

* feat: Send GutenbergKit the latest content when requested

Allow GutenbergKit to retrieve the latest content persisted in the host
app as needed. This is important for allowing GutenbergKit to display
the latest content after the WebView reloads or re-initializes from
memory pressure or backgrounding.

* feat: Set GutenbergKit post status

* build: Update GutenbergKit version

Integrate an unrelated content loss fix that is necessary for testing
this branch's focus on content preservation.
