PSA test case generation: dependency inference class: operation fail

Browse Source 
Use psa_information.TestCase for operation failure test cases.

This changes the generated output in two ways:

* Not-implemented mechanisms now have a `DEPENDENCY_NOT_IMPLEMENTED_YET_xxx`
  dependency in addition to the never-fulfilled `PSA_WANT_xxx` dependency.
  This does not affect when test cases run.
* ECC test cases now have correct dependency symbols, e.g.
  `PSA_WANT_ECC_SECP_R1_192` instead of `PSA_WANT_ECC_FAMILY_SECP_R1`. This
  is a bug fix: ECC test cases were formerly never executed because of
  incorrect dependency symbols.
