completions/zsh: Improve caching behaviour

Browse Source 
Fixes #5839

- Eliminate reliance on external utility calls for cache invalidation
- Update cache policy to also invalidate if cache file is >=2 weeks old or if
  tap indexes are non-existent
- Do not override any cache policy the user might already have set
- Handle default cache policy determination as early as possible to ensure that
  a default is set appropriately for all helpers (this will mostly be useful if
  other helpers need caching in the future)
