Move members that are of no use to the PSA crypto core

For cipher multi-part operations, dispatch based on
the driver identifier even in the case of the
Mbed TLS software implementation (viewed as a driver).
Also use the driver identifier to check that an
cipher operation context is active or not.
This aligns the way hash and cipher multi-part
operations are dispatched.

To run succesfully the test
"PSA sign: invalid algorithm for ECC key" of
test_suite_psa_crypto when ECDSA support is not included
in the library, always return INVALID_ARGUMENT
in case of an ECC key not used for ECDSA, whether
ECDSA support is present or not.
Then apply the same logic to RSA sign RSA and RSA/ECC
verify for the sake of consistency.

For the time being, it is not possible to determine
the size of ECC keys from the arguments of all test
cases thus treat them as dependencies that are not
systematic. Such dependencies are not generated nor
deleted by set_psa_test_dependencies.py.

Fix likely harmless undefined behavior in cipher tests pointed out by
UBSan with recent compilers (e.g. Clang 10). When the complete output
is empty, the output buffer is NULL. Adding an integer to a null
pointer is undefined behavior even when the integer is 0, so make a
special case for that.

If an elliptic curve was enabled in the Mbed TLS classic API (#define
MBEDTLS_ECP_DP_xxx), but not enabled in the PSA configuration (#define
PSA_WANT_ECC_xxx), it would still work if you tried to use it through
PSA.
This is generally benign, but could be a security issue if you want to
disable a curve in PSA for some security reason (such as a known bug
in its implementation, which may not matter in the classic API if Mbed
TLS is running in a secure enclave and is only reachable from
untrusted callers through the PSA API). More urgently, this broke
test_suite_psa_crypto_not_supported.generated.
So if a curve is not enabled in the PSA configuration, ensure that
it's treated as unsupported through the PSA software implementation.
