Themes: Improve reliability of URL used in get_header_image_tag().

`get_header_image_tag()` relies on the data returned by `get_custom_header()`
to build the attributes for the header `<img>` element. However,
`get_custom_header()` relies on data from the `header_image_data` theme
mod rather than the `header_image` theme mod that `get_header_image()` uses.
This can create inconsistencies when no header image is set, but a theme
supports a default header image.

This fixes the issue by making `get_custom_image_tag()` rely on the URL
returned by `get_header_image()` instead.

Props bradyvercher.
Fixes #38633.
