CloudFlare Analytics: move feature to mu-wpcom (#37061)

* CloudFlare Analytics: move feature to mu-wpcom

The feature is only used on WordPress.com sites, it is not needed in the Jetpack plugin.

Since the feature was loaded on all connected Jetpack sites, it also had the inconvenient of making an option call on every frontend call.

* Update Phan config

* Stop loading the Jetpack module

* Update projects/packages/jetpack-mu-wpcom/src/features/cloudflare-analytics/cloudflare-analytics.php

* Fix PHPCS error
