Remove 16 redundant skipped test stubs in test_scalars.py (#21026)

Summary: These test functions are empty stubs (body=pass) that are
permanently skipped because their functionality is tested by the
corresponding _tosa_INT and _tosa_BI tests. Removing them reduces the
ai_infra_mobile_platform oncall's SKIPPING count by 16.
