QtSupport: Replace BaseQtVersion::clone()

... by a mechanism that doesn't require re-implementation in each
derived class.

A QtVersion's type() is uniquely defined by the supported type of
the factory creating it, so that factory can be found and used
for cloning. Non-base data is copied by a fromMap(toMap()) dance
as done in the project configurations.

As a side-effect, the *QtVersion copy constructors are not used
and not needed anymore.
