manual: get rid of the lists of packages

We currently have four lists of packages in the manual:
  - the non-virtual target packages,
  - the virtual target packages,
  - the host packages,
  - the deprecated features.

Those list take more than half of the manual. They do not serve much
purpose except to show off.

After the recent discussion on the list [0], remove them all.

We can now get rid of our biggish and complex generating script (and its
companion library kconfiglib).
