Make PSA headers more self-contained

Several files among include/psa/crypto_*.h are not meant to be included
directly, and are not guaranteed to be valid if included directly. This
makes it harder to perform some static analyses. So make these files more
self-contained so that at least, if included on their own, there is no
missing macro or type definition (excluding the deliberate use of forward
declarations of structs and unions).
