libyogrt package: add versions, scheduler support (#10884)

* Add latest libyogrt versions
* Add url_for_version to handle differing url formats for different
  versions
* Add 'scheduler' variant to configure scheduler. Currently only
  slurm can be installed with Spack. A value of 'system' indicates
  to use the scheduler installed on the system
