Rename psa_helpers.function to psa_crypto_helpers.h
This file isn't like the other .function files: it isn't concatenated
by a separate preprocessing script, but included via C preprocessing.
Rename this file to .h. This isn't a normal C header, because it
defines auxiliary functions. But the functions aren't big and we only
have one compilation unit per executable, so this is good enough for
what we're doing.
