spacedmonkey f19df46584 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.
