Remove the GENERIC_ERROR return behaviour, in favour of returning the actual status.

All current usages have this parameter set to 0 (meaning the behaviour
of these tests hasn't changed). We also now return the actual error code, not GENERIC_ERROR

This will allow us to use this smoke test to ensure that key slot content reads are
only performed when we are registered to read a full slot. We will destroy the key
on another thread while the key is being exercised, and fail the test if an unexpected
error code is hit. Future commits will incrementally implement this new parameter.
All current usages of this function have this parameter set to 0, in which case
the new behaviour must be the same as the old behaviour

Split into n threads, each thread will repeatedly generate,
exercise and destroy a key.
Then join the threads, and ensure using PSA_DONE that no keys still exist.

Remove the ability to select a custom public exponent via domain parameters
in RSA key generation. The only way to select a custom public exponent is
now to pass custom production parameters to psa_generate_key_ext().
A subsequent commit will remove domain parameters altogether from the API,
thus this commit does not bother to update the documentation.

"Key generation method" was misleading since it also applies to key
derivation. Change "key generation" to "key production", which we aren't
using yet and has roughly the right intuition. Change "method" to
"parameters" which there seems to be a slight preference for. Discussion

Assigning the return value of a function that returns a struct with a
flexible array member does not fill the flexible array member, which leaves
a gap in the initialization that could be surprising to programmers. Also,
this is a borderline case in ABI design which could cause interoperability
problems. So remove this function.
This gets rid of an annoying note from GCC about ABI compatibility on
(at least) x86_64.

Instead of passing the size of the whole structure, just pass the data
length and let the implementation worry about adding the size of the
structure. The intent with passing the structure size was to allow
the client code in a client-server implementation to know nothing
about the structure and just copy the bytes to the server. But that was not
really a useful consideration since the application has to know the
structure layout, so it has to be available in the client implementation's
headers. Passing the method data length makes life simpler for everyone by
not having to worry about possible padding at the end of the structure, and
removes a potential error condition
(method_length < sizeof(psa_key_generation_method_t)).

`psa_get_key_attributes` depends on some built-in
implementation of RSA. Guard the check with coresponding
