Joe McGill b4a6b21986 Upgrade/Install: Skip registering theme block patterns during the upgrade process.
This fixes a bug during the database upgrade process where a theme's `functions.php` file may not be loaded, leading to potential exceptions if the theme's pattern files use symbols (classes, functions, constants, etc.) that are declared only when the `functions.php` file is loaded. To do so, a check for `wp_get_active_and_valid_themes()` is added early to `_register_theme_block_patterns()`, which returns early if no active or valid themes are returned.
