Enhance Civictheme menu theming system

Problem/Motivation

At the moment we hardcode menu names to the theming layer, we should define primary, secondary, footer menus in theme settings and theme these blocks accordingly.

• see: civictheme_preprocess_block__menu_block__civictheme_primary_navigation for hardcoding theme preprocess
• and menu.inc see: _civictheme_preprocess_block__navigation and _civictheme_preprocess_block__civictheme_footer_menu
