generate_psa_tests: use automatic dependencies for positive test cases

This causes more test cases to be commented out due to mechanisms that are
not implemented, because the code `generate_psa_tests.StorageFormat` was not
trying to skip never-supported dependencies.

To review for correctness, filter the diff of the generated files as
follows to find new skip reasons:
```
grep -E '^\+## # skipped because' | sort -u
```
And check that none of the appearing mechanisms are implemented.
