BareMetal: Use the plain creation and fromMap(toMap()) for clones

This allows to drop the hierarchy of copy constructors and makes
the setup more similar to what various other factory types in
the ProjectExplorer use nowadays.

This slightly changes clone() behavior in some cases. If that's
not considered harmless, we can introduce some 'polishAfterClone'
or similar.
