New test suite for systematically generated operation failure tests
The new test suite psa_crypto_op_fail is intended for systematically
generated test cases that ensure that cryptographic operations with
invalid parameters fail as expected. I intend invalid parameters to
cover things like an invalid algorithm, an algorithm that is
incompatible with the operation, a key type that is incompatible with
the algorithm, etc.
This commit just creates the infrastructure. Subsequent commits will
add data generation and test code.
