refactor: one site-wide Divi cache clear and one compatibility row (review M-1, M-2)

DiviSaver's site-wide scopes and the Theme Builder tools now share
DiviThemeBuilder::clearSiteCaches(), which clears the Theme Builder cache
even when ET_Core_PageResource is missing. lit-site-status no longer lists
et_theme_builder_clear_wp_cache twice: the Theme Builder functions row
covers it, and the post-type row uses DiviThemeBuilder::postTypes().
