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).

Using static inline functions is bad for code size; the function from
md_internal.h was already used from 3 different C files, so already was
copied at least 3 times in the library, and this would only get worse
over time.
Use actual functions, and also share the actual data between them.
Provide a consistent set of operations. Conversion to/from
human-readable string was omitted for now but could be added later if
needed.
In the future, this can be used to replace other similar (inline)
functions that are currently scattered, including (but perhaps not
limited to):
- mbedtls_psa_translate_md() from psa_util.h
- mbedtls_md_info_from_psa() (indirectly) from psa_crypto_hash.h
- get_md_alg_from_psa() from psa_crypto_rsa.c
