Sync Package: Moves the Protect sync module

[roccotripaldi]

We are trying to move away from class mapped packages, and unspool all of the dependencies within a package.

So let's do this!

Part of #12712

Changes proposed in this Pull Request:

This PR should have no functional changes. The Protect sync module should function exactly the same as before.

Note, the Protect module will need its own package, but we'll handle that in an other PR.

Is this a new feature or does it add/remove features to an existing part of Jetpack?

This modifies an existing part of Jetpack.

Testing instructions:

• Try this branch out on a Jurassic.ninja site or on your docker testing site.
• Connect the site and activate the recommended features.
• Point your testing site to your .com sandbox to observe sync actions in real time.
• Log out of your testing site, and login with a incorrect username / password
• Do you see the sync action for jetpack_valid_failed_login_attempt
