 This PR backports core PHP changes from Gutenberg
 (https://github.com/WordPress/gutenberg/pull/74968) that remove the
 overlay experiment and migrate navigation overlay patterns to use the core
 namespace.

 This backport includes the following core changes:

 - Navigation Pattern Category: Adds the navigation block pattern category
 registration in block-patterns.php.

 - Navigation Overlay Patterns: Adds five new navigation overlay block
 patterns.

 - Template Part Area Constant: Adds the
 WP_TEMPLATE_PART_AREA_NAVIGATION_OVERLAY constant and corresponding area
 definition in block-template-utils.php to support navigation overlay
 template parts.

 This backport is based on changes from WordPress/gutenberg#74968
 Testing

 - Verify navigation pattern category appears in the block pattern inserter
 - Verify all five navigation overlay patterns are available and render
 correctly
 - Verify navigation overlay template parts can be created and used
 - Test pattern insertion in the site editor
