This adds around 40 more tests per platform. The runtime of GHA seems to have a lot of run to run variance. Most new tests are in the `hs/tier1 gc` which has a lower runtime than a few other jobs. So until the heavies jobs gets split into multiple jobs,   this should have a negligible affect the overall GHA runtime
