Avoid clone on entry to `BasisTranslator` (#14761)

The Rust-space method takes ownership of the `DAGCircuit` so that the
return type can be a unified `PyResult<DAGCircuit>`, even though in the
majority case, the pass actually builds a completely new DAG.  This
unfortunately requires an implicit clone on entry from Python space,
even though there is no situation where the clone is actually
_necessary_; the rebuild form never mutates the input, and in the
fast-return paths, Python space can simply continue using the reference
to a `DAGCircuit` it already holds.
