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).

In principle, the case where neither SHA-256 nor SHA-384 are available
should never occur, as both TLS 1.2 and TLS 1.3 depend on one of those
being defined. However for now dependencies for TLS 1.2 are not as tight
as they should be; this will be fixed later and is tracked as #6441.

That's the last family of functions. All calls to mbedtls_sha* and
psa_hash_* in library/ssl_tls.c are now checked for errors.

On top on some calls not being checked, the PSA path was missing a call
to abort() on errors.

A few functions were changed from returning void to returning int three
commits ago. Make sure their callers check the return values.
This commits was basically a matter of declaring newly-int-returning
functions MBEDTLS_CHECK_RETURN_CRITICAL and then fixing the resulting
warnings. A few functions had to be made int in the process; they were
applied the same process as well.

This part can fail, so it shouldn't be intermixed with the part that
can't fail and is there to ensure all structures are in a clean state,
should any error happen.
Fortunately, the part that should be split out already had a function
doing it: reset_checksum. Also, handshake_params_init had only one
calling site to update.

There are three family of functions: update_checksum, calc_verify,
calc_finished, that perform hashing operations and were returning void
so far. This is not correct, as hashing functions can return errors (for
example, on hardware failure when accelerated). Change them to return
int.
This commit just changes the types: for now the functions always return
0, and their return value is not checked; this will be fixed in the
next few commits.
There is a related function in TLS 1.3,
mbedtls_ssl_reset_transcript_for_hrr, which also handles hashes, and
already returns int but does not correctly check for errors from hashing
functions so far, it will also be handled in the next few commits.
There's a special case with handshake_params_init: _init functions
should return void, so we'll need to split out the part that can return
errors, see the next commit.

When ticket_flags used as parameter, use unsigned int,
instead of uint8_t or mbedtls_ssl_tls13_ticket_flags.Also
remove the definition of mbedtls_ssl_tls13_ticket_flags.

Some PSA curves' symbols (PSA_WANT_) were not matching the corresponding
MBEDTLS_ECP_DP_. This was fixed together with the removal of extra code
when DEBUG_C is not enabled.

It might happen that the psa_pake_output() function returns
elements which are not exactly 32 or 65 bytes as expected, but
1 bytes less.
As a consequence, insted of hardcoding the expected value for
the length in the output buffer, we write the correct one as
obtained from psa_pake_output()
