Joe McGill 299978551a Themes: Improve error notice when wp_is_block_theme() is called too early. ...

This is a follow-up to [59968] which improves error handling for when `wp_is_block_theme()` is called too early. Initially, `_doing_it_wrong()` was called in `WP_Theme::is_block_theme()` was called prior to themes being set up, in order to avoid the bug reported in #63062, where doing so would cause parent themes to not be resolved. After further investigation, the issue is only caused by calling `wp_is_block_theme()` before the root theme directory has been registered (e.g., when called on the `muplugins_loaded` hook).

Moving This error message to `wp_is_block_theme()` when `$GLOBALS['wp_theme_directories']` is empty avoids unnecessary error messages.
