Add block/shortcode usage to Cart and Checkout pages in system report (#48300)

* Refactored get_pages() to reduce the amount of get_post() used, avoid unnecessary ifs, and fixed a bug where the classic shortcode block would trigger a false block usage value.

* Added block/shortcode usage to the system report for the Cart & Checkout pages. Also added a warning when a page contains both experiences.

* Added support info for templates out of sync not loading the page content.
