Subject: [PATCH] Accessibility: Customize: Add an empty `alt` attribute to the
 `<img>` tag used as a hidden placeholder in the Customizer preview when no
 logo is chosen.

Per accessibility best practices, it is recommended that all HTML `<img>` elements have an `alt` attribute. Any decorative images should have an empty `alt` attribute (`alt=""`).

Props laxman-prajapati, sabernhardt, audrasjb.
Fixes #51846.
