WIP: Run two tests with KMP_TOPOLOGY_METHOD=cpuinfo for GHA runners

The runners currently have 4 virtual cores; 2 cores with
2 threads each.

This is exposed correctly via cpuinfo, but by default libomp
picks this up via __kmp_affinity_create_apicid_map, which
gets it wrong. Unclear if this is a bug with that function,
or if it is a virtualization bug.
