Fix `ApplyLayout` with empty layout (backport #14606) (#14615)

* Fix `ApplyLayout` with empty layout (#14606)

It's unlikely to ever be useful, but strictly there still is a
well-defined behaviour for `ApplyLayout` on a zero-qubit circuit and
backend.  Previously, the pass errored out falsely asserting user error.

(cherry picked from commit d0630fd19)

* Use PassManager for empty layout tests.

* Use dummy pass for test_empty_post_layout.

* Ignore lint.
