Release 0.13.2 (#2031)

* PR to release 0.13.2

* Remove usage of ``qiskit.extensions`` (#2023)

The module has been pending deprecation since Qiskit 0.45.
It is deprecated for 0.46 and removed in 1.0.

This removal concerns the import location of ``UnitaryGate`` and the
usage of the ``ExtensionError``. The first is easily fixed, whereas for
the latter I tried using ``ValueError`` or ``TypeError``, which seemed
to cover the error meanings. Technically, this is a breaking change and
we could introduce an intermediary class that inherits from the deprecated
``ExtensionError`` and the new choice of error. However, since we will
soon be changing to 1.0 and we also skipped this in Qiskit Terra (as we
thought it highly unlikely that users are actually relying on this error
type) it might be fine to just change the error type.

* Fix GPU batched execution (#2014)

* Fix GPU batched execution

* format

* Use Apple-specific API to determine system memory on macOS (#2016)

The unistd.h API that had been used for both Linux and macOS is not
always available in macOS environments, for example when building with
upstream clang rather than AppleClang.

Closes #1923

* Remove qiskit.test from test/common.py (#1971)

* remove qiskit.test from test/common.py

* Add support for running with Python 3.12 (#2022)

* Add support for running with Python 3.12

Python 3.12.0 was released on 10-02-2023, this commit marks the start
of support for Python 3.12 in qiskit-aer. It adds the supported Python
version in the package metadata and updates the CI configuration to run
test jobs on Python 3.12 and build Python 3.12 wheels on release.

* Remove numpy constraints

* Uncap six

* Fix i686 build steps

* Use python 3.12.0 in tests to work around unittest breakage in 3.12.1

* Use 3.12.0 for all test jobs
