Add per-page caching of filtered and rendered tours

This extension is being deprecated, see 🌱 [Meta] Tasks to deprecate Tour module Fixed . It will be removed from core and moved to a contrib project, 📌 [11.x] [Meta] Tasks to remove Tour Postponed .

This is now Postponed. The status is set according to two policies. The Remove a core extension and move it to a contributed project → and the Extensions approved for removal → policies.

@larowlan would you mind looking at the tour_toolbar() for the 2.0.x branch of contrib to see if the issue you saw still exists?

We've added a bit of caching in 2.0.x version so believe this may be outdated.

If I'm wrong please reopen.
