closes https://github.com/TryGhost/Product/issues/3803

Previously when the beta editor was enabled, using `?source=html` to create posts via the API would create posts in the old editor rather than the beta. This change switches conversion over to the new editor format when the beta is enabled so the full flow can be tested.

- added `htmlToLexicalConverter` method to our lexical library
- updated post and page input serializers to add html-to-lexical conversion when the beta editor is enabled
- updated post model to handle the mobiledoc+lexical co-existing state
  - this is a special case that is only valid for `?source=html` because providing both directly via the API is prohibited
  - we need the extra check here because at the input serializer layer we don't have access to the model to check if we're updating a mobiledoc post or a lexical post so the serializer sets both formats on a `?source=html` request when the beta is enabled and lets the model handle choosing the correct one
