tests: Try heavier SAE groups in sae_groups

Browse Source 
This changes the sae_groups test case design to try with every group and
skip triggering test failure for the heavier ones that are likely to
fail in some VM setups under load. This provides more testing coverage
by not limiting the test based on lowest common setup.
