Fix optional parameter handling in crypto service

The psa_crypto api mandates that the optional 'salt' parameter passed
to psa_asymmetric_encrypt/decrypt should be NULL if there is no
salt.  This fix modifies packed-c encoding to omit the salt TLV
if not needed.  Deserialization logic is also made more tolerant
to a missing or zero length salt parameter.  A new test case
is added to cover an asymmetric encrypt/decrypt with a salt.
