Propagate `DAGCircuit.name` in `ApplyLayout` (#13910) (#13920)

* Propagate `DAGCircuit.name` in `ApplyLayout`

This has always been absent, but `transpile` masked the problem by
assigning the output circuit names by overwriting the `output_names`
input kwarg if it wasn't set.  `generate_preset_pass_manager` didn't
have the same logic, so it was observable that `ApplyLayout` didn't
propagate the name.

We could have added similar name-propagation logic to
`generate_preset_pass_manager`, but really the bug is in `ApplyLayout`;
passes _should_ propagate the metadata.
