Add GutenbergKit

• Feature: Android - Add initial Editor params GutenbergKit#23

This PR adds GutenbergKit behind a feature flag. Due to the complexity of the editor setup in the app, I incorporated the new code into existing files, which made it difficult to work with the mixed Java and Kotlin files.

Most of the editor's functionality should be working, although I disabled some UI elements, such as the undo/redo buttons and certain menu items, until we add support for them.

Current feature support:

• Create posts and pages
• Use page layouts from the picker
• Blogging prompts
• Share a website into the editor
• Copy/paste an image into the editor
• Restore the editor's state if the activity is closed
• Upload media from the device’s files within the editor
• Preview posts/pages
• Sync content changes as you type
• Auto-save when closing the editor
• Discard creating a draft if the post is empty (title and content)

---

To Test:

Note

Precondition: Enable the feature flag, Go to the Me tab > Debug settings > experimental_block_editor

Smoke test the current editor

To make sure no regressions were added, smoke testing the current editor would be great, adding some texts and media to make sure it works as expected.

Regression Notes

1. Potential unintended areas of impact

   • It should only affect the new editor but smoke testing the production version would be good too.

2. What I did to test those areas of impact (or what existing automated tests I relied on)

   • Manual testing

3. What automated tests I added (or what prevented me from doing so)

   • No new tests were added.

PR Submission Checklist:

• I have completed the Regression Notes.
• I have considered adding accessibility improvements for my changes.
• I have considered if this change warrants user-facing release notes and have added them to RELEASE-NOTES.txt if necessary.

Testing Checklist (strike-out the not-applying and unnecessary ones):

• WordPress.com sites and self-hosted Jetpack sites.
• Portrait and landscape orientations.
• Light and dark modes.
• Fonts: Larger, smaller and bold text.
• High contrast.
• Talkback.
