Checks that the active theme has the required files.

Standalone themes need to have a templates/index.html or index.php template file. Child themes need to have a Template header in the style.css stylesheet. Does not initially check the default theme, which is the fallback and should always exist. But if it doesn't exist, it'll fall back to the latest core default theme that does exist. Will switch theme to the fallback theme if active theme does not validate. You can use the {@see 'validate_current_theme'} filter to return false to disable this functionality.
