Reader: Update the main tabs

[kean]

Changes:

• Rename "Recent" tab to "Home" (and introduce a separate ReaderHomeViewController)
• Add "Create Post" navigation bar button on the "Home" screen
• Remove scroll-to-top button. Based on analytics, people don't use it, and, unlike jpios, you can just tap on the tab bar item now
• Implement scroll-to-top by tapping on tab bar items
• Update the "Following" screen: add tabs to show your lists and tags, fix push on selection, add support for adding items, etc
• Add search to "Discover"
• Bind notifiations badge on tab bar item
• Add new "Me" Reader-specific tab. It shows site dashboard, your profile card, and allows you to open the regular "Me" screen with profile settings

Note: take into account that this not production code. It was created as quickly as possible so we could ship a prototype. It will not affect the main apps, but there are a few places where I needed to update the production code – this will need to be checked.

To test:

• Change the "WPAppBrand" value in the Jetpack app to "reader"
• Follow the changes – smoke test

Regression Notes

1. Potential unintended areas of impact

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

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

PR submission checklist:

• I have completed the Regression Notes.
• I have considered adding unit tests for my changes.
• 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:

• WordPress.com sites and self-hosted Jetpack sites.
• Portrait and landscape orientations.
• Light and dark modes.
• Fonts: Larger, smaller and bold text.
• High contrast.
• VoiceOver.
• Languages with large words or with letters/accents not frequently used in English.
• Right-to-left languages. (Even if translation isn’t complete, formatting should still respect the right-to-left layout)
• iPhone and iPad.
• Multi-tasking: Split view and Slide over. (iPad)
