WP_Debug_Data: Extract wp-dropins data into separate method.

This is the seventh 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 seventh of twelve groups, the `wp-dropins` 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.
