Commit Message

Update transpiler pipeline to (only) use target internally (#12850)

* First attempt at supporting a virtual target (FakeTarget) with no basis gates in the preset pass managers.

* Remove prints

* Fix control-flow failures with fake target

* Fix init stage, add instruction_supported method to FakeTarget

* Tweak preset pass manager

* Handle inst_map deprecation warning

* Handle annotated operations

* Do not skip stages with FakeTarget

* Deprecate custom basis gates

* Cleanup

* Remove reno

* Refactor creation of _FakeTarget, add tests

* Fix handling of pre-optimization stage and gate direction passes

* Restore cargo.lock

* Address most lint complaints

* Fix dt issue

* Address HLS issue

* Address GateDirection issue

* Fix lint and improve style

* Refactor plugin logic, handle target with no basis gates at the pass level (Python interface only) instead of pm level.

* Remove deprecated arguments: instruction_durations, timing_constrants and custom basis_gates.
Do not skip target unless dictated by backend. Add warning for backend + loose constraints and
raise error if basis_gates contains 3q+ gates with a coupling map, as this generates a conflic
in the model where it's not clear to which qubits the gates can apply. This is a limitation that
comes from Target.from_configuration, but it's more user-friendly to raise the error from
generate_preset_pass_manager.

* Apply suggestions from Eli's code review
