WordPress.com authentication via web view

[crazytonyli]

Implement WordPres.com's oauth2 flow. At the moment it's only used when self-hosted site user tries to log in WordPress.com from the Me tab.

To test: Add a self-hosted site to the Jetpack app, go to the Me tab, and tap the "Log in" button.

I tested it in a simulator and it worked really well. I'm looking forward to when it's integrated in the main flows so I could test it with passkeys.
