Fix: Check if email verified before allowing to update avatar

[AdamGrzybkowski]

There was a backend fix applied at Gravatar to disallow using authenticated endpoints with account that hasn't verified the email. Using authenticated endpoint creates a Gravatar profile, but this shouldn't happen if email is not verified.

This means that before uploading a photo (via REST API or QuickEditor) we need to make sure the email is verified. If not, a proper message should be shown to the user.

This is the corresponding iOS PR. The copy for the message matches it as well.

Here's how it looks:

---

To Test:

1. Create a new account without verifying the email (I was only able to do it via web)
2. Login in the Jetpack app
3. Got the the me section
4. Tap on the avatar in the top left
5. Confirm you see a snack with the proper message about unverified email
6. Log out and log in with your standard account
7. Repeat steps 3 and 4 and confirm the Quick Editor was shown
8. You can also disable the gravatar_quick_editor feature flag to test the old flow, but the email verification check is the same so if the above works, this should too.

@AdamGrzybkowski This looks good and I'll approve it. I left a comment about the placement of the new string resource, but it's not a big deal at all. I'll leave it to you whether to make the change, and you can merge when ready.
