Export: Include featured image for posts or pages. 

This bugfix resolves an issue in `export_wp()` with featured images.

When using Tools > Export and selecting either Posts or Pages (with or without a specific author), the resulting XML file now includes a XML item for each post|page's featured image attachment and its metadata.

Uses same chunking (for performance) and code patterns from existing code in the same file.

Adds a new test class for `export_wp()` with code coverage specific to this bugfix.

Follow-up to [34326], [14444], [6375], [6335].
