openmm/openmm: OpenMM 8.5.0

This release adds the following new features. The energy minimizer has been rewritten to run entirely on the GPU. This can make energy minimization dramatically faster. PythonForce is a new class that can be used to compute forces and energies with Python code. The most important application is machine learning potentials; it allows us to support a much larger range of ML potentials than was possible before. It can also be used for arbitrary other forces, but it has relatively high overhead. If a force can be implemented with the existing custom forces, that is usually a better choice. LCPO has been added as another option for computing the surface energy term in implicit solvent simulations. It is more accurate than the default ACE approximation, but also slower. We have made internal changes needed to support the next generation OpenFF force fields. There is a new API to query what devices are available before starting a simulation. When loading Gromacs files, one additional type of vsite is supported.
