Remove legacy code to compute geometry

This code is not necessary anymore after the fix to #13069.

Remove the first QString argument to createView(). Set the autoShow
parameter to false by default and rename createView(id) to
createAndShowView(id) to avoid member function overloading issues.

Remove optional <GEOMETRY> argument of window-new lfun.
Document the removal of the argument in release notes.
