Unify PSA to Mbed TLS error translation

Move all error translation utilities to psa_util.c.
Introduce macros and functions to avoid having
a local copy of the error translating function in
each place.
Identify overlapping errors and introduce a
generic function.
Provide a single macro for all error translations
(unless one file needs a couple of different ones).
