Create a framework for PSA test cases with automatic dependencies

The new class `psa_test_case.TestCase` will automatically infer dependencies
from the test data. The dependency inference is not done yet, this will be
implemented in subsequent commits.

No change to any generated file since this new module is not used yet.
