 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.

 Fixes #63086. See #63062.
