bitbake: toaster: blocks for custom/highlighted navigation and breadcrumb links

Implement the navigation links as blocks so that each page can override and have
its respective link appear highlighted. Make the build breadcrumb a block so that
it is customizable to not be a link for the dashboard page. Reorder the page headers
to be consistent order for extends, projecttags, localbreadcrumb, nav-links.
