Fix handling of control flow instructions in convert_to_target() (#11922)

* Fix handling of control flow instructions in convert_to_target()

This commit fixes an issue in the convert_to_target() function where it
wasn't looking for control flow instructions in the proper location.
Typically the control flow instructions are put in the
supported_instructions field of the BackendConfiguration, but the
convert_to_target() function was ignoring this field. This commit
updates the function to check supported_instructions for the control
flow instructions. It doesn't more broadly look at the
supported_instructions field, because on other backends this field is
used to list the supported pulse instructions which might have name
conflicts with other instructions and cause issues building a target.

This is the spiritual backport of #11877, but because the state of the
convert_to_target() function on stable/0.46 is very different very
little code is carried over from the version on main and stable/1.0,
basically only the tests. This is actually closer in implementation to
the equivalent PR on qiskit-ibm-runtime: Qiskit/qiskit-ibm-runtime#1443
as the internal conversion function in that repository is very similar
to the function on the stable/0.46 branch.

* Add release note

* Fix tests

* Fix import cycle
