 tentative improvement to callstack docs

 This is an attempt at clarifying the docs for HasCallStack in both the
 user guide and libraries/base/GHC/Stack/Types.hs. The example used right
 now is built around an hypothetical 'error' function that doesn't itself
 print call stacks, and the fact that this doesn't hold makes it all
 confusing, see #14635.
