psa_key_slot_t: different fields in free vs occupied slots

Place some fields of psa_key_slot_t in a union, to prepare for a new field
in free slots that should not require extra memory.

For occupied slots, place only the registered_readers field in the union,
not other fields, to minimize textual changes. All fields could move to the
union except state (also needed in free slots) and attr (which must stay
first to reduce the code size, because it is accessed at many call sites).
