context_processors: Use breadcrumbs to highlight current section
- We were using hacky logic of assuming that if a page using the URL
/plinth/sys/..., then it belongs to 'system' section based on the URL match.
This won't work when the URL does not follow this pattern for any reason.

- Instead use the breadcrumbs mechanism which uses menu items and URL names to
determine the section a page belongs to.

Tests:

- Visit page, apps page, system page, help pages, an app page in apps sections,
an app page in system section, backups -> create backup page and notice that the
correct section is highlighted.
