Use QQmlRefCount for QQmlType(Private)

As we already have an implementation of refcounting, we can just use
that intead of inventing another one. This also gives us nice move ctors
and operators.

Also, use const pointers to QQmlTypePrivate where possible. This exposes
quite some nastiness that needs to be fixed in follow-up commits: All
the mutable members of QQmlTypePrivate are unsafe for multithreaded use.
