COMP: Re-enable CXX CI with system package inputs for OpenSlide

Re-enable the CXX build workflow using the new apt-packages,
brew-packages, and os-list inputs from
ITKRemoteModuleBuildTestPackageAction to install OpenSlide on
Linux and macOS runners. Windows is excluded via os-list because
OpenSlide has no Windows package manager distribution.

Python wheel builds remain disabled because OpenSlide is not available
in the dockcross manylinux containers used for wheel building.

Also updates minimum Python version to 3.10+.
