Support Python 3.12 (#6516)

- Fix attribute error in `engine_test.py::test_create_context`
- Adjust package presence assertion in `test_isolated_env_cloning`
- Bump up to virtualenv>=20.23, filelock~=3.1, pylatex~=1.4
- Bump up to grpcio-tools~=1.59.0 and recompile protos
- Relax qiskit-aer requirement to qiskit-aer~=0.12.0.  Allow qiskit-aer-0.12.0
  which has source archive on PyPI and can be installed for Python 3.12.
- Bump up to quimb~=1.7 which installs correctly with Python 3.12
  Remove quimb-only dependencies from our requirements, let
  quimb sort out its dependencies itself.
- CI - add pytest jobs with Python 3.12
- Skip mysteriously failing test of Contract-a-Grid-Circuit.ipynb

Fixes #6460
