Add a py-gmxapi package. (#35738)

Browse source 
* Add a `py-gmxapi` package.

This package provides the Python package for the GROMACS
public API. The Python package is not strongly coupled to
a specific GROMACS _version_, but its compiled extension module
is strongly coupled to a specific GROMACS _installation_.

* Update conflict info.

In order to allow `^gromacs@2022.1` while rejecting `^gromacs@2022`,
we need to compare to `gromacs@2022.0`.

* Apply suggestions from code review

* Apply suggestions from code review.

* Simplify build system structure.
* Update dependencies for completeness.

* Update var/spack/repos/builtin/packages/py-gmxapi/package.py

Per code review, pretend gmxapi <0.4 doesn't exist, for simplicity.

* Update var/spack/repos/builtin/packages/py-gmxapi/package.py
