This is the ninth part in a larger modularization of the data in `WP_Debug_Data`. Previously this was a single massive method drawing in debug data from various groups of related data, where the groups were independent from each other.

This patch separates the tenth of twelve groups, the `wp-core` info, into a separate method focused on that data.

This work precedes changes to make the `WP_Debug_Data` class more extensible for better use by plugin and theme code.

Developed in https://github.com/wordpress/wordpress-develop/pull/7357
Discussed in https://core.trac.wordpress.org/ticket/61648
