crypto-client test: implement the first IPC call for psa_crypto_init()
This commit implements the first useful IPC communication between
the client and the server. The implemented command is simple,
psa_crypto_init(), and its return value is sent back to the client.
Note: the newly added file psa_functions_codes.h is temporary
and it's probably the one that needs to be automatically
generated by a python script to support all crypto functions.
