Write tour integration for block_content.module

This tour module 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.

I have integrated tour for custom block, attached the screenshots, not sure apart from it, nothing seems to be left.
