Bundled Theme: Implement the_header_image_tag function for enhanced compatibility for older core themes.

The the_header_image_tag function was introduced in WordPress 4.4 as part of [35594]. It is used in all themes created post WordPress 4.4 that supported header images. The function get_header_image_tag continues to get updated with new image features, like lazy loading, async decoding and fetch priority. To ensure our core themes maintain compatibility and benefit from these enhancements, a backward compatibility shim has been applied, integrating the the_header_image_tag function into the following core themes:

  • Twenty Ten
  • Twenty Eleven
  • Twenty Twelve
  • Twenty Fourteen
  • Twenty Sixteen

This change ensures future compatibility and modern image features are applied for header images to these older themes.

Props spacedmonkey, flixos90, mukesh27.
Fixes #58675.
