Designer: Restore and move NewClassWizard from Utils to Designer

Commit a8af381 prematurely deleted newclasswizard.cpp/h/ui although they
are still used by the Designer plugin. That caused a build breakage.

This change partially amends a8af381 and moves the code into the
Designer plugin. Unneeded code got removed.
