Issue 7529 uncovered an unrequired check in a for loop
condition in ssl_tls.c. This commit removes said check.

Note = programs are not aligned to this change because:
- the original mbedtls_pk_ec is not ufficially deprecated
- that function is used in tests when ECP_C is defined, so
the legacy version of that function is available in that
case

Set hybrid TLS 1.2/1.3 as default server
configuration if both TLS 1.2 and TLS 1.3
are enabled at build time.

The function reset_checksum() can be called more than once with the same
handshake context (this happens with DTLS clients, and perhaps in other
cases as well). When that happens, we need to free the old MD contexts
before setting them up again.
Note: the PSA path was already doing the right thing by calling abort,
we just needed to do the same on the MD path.

With the introduction of #7047, ssl_tls.c uses
mbedtls_md_error_from_psa. This complicates
the dependencies for compiling in psa_to_md_errors,
since now these should be ifdeffed also by
MBEDTLS_USE_PSA_CRYPTO followed by a series of or'ed
MBEDTLS_HAS_ALG_SHA_XXX_VIA_MD_OR_PSA_BASED_ON_USE_PSA.
Since this mechanism will be removed soon, we can simplify it to
just MBEDTLS_USE_PSA_CRYPTO.

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).

The name sha512 might have made sense when it was an
mbedtls_sha512_context, but now it's weird to see things like
mbedtls_md_setup(&sha512, ...MBEDTLS_MD_SHA384...);

There's little reason for accessing the hash implementation's internal
state, its output contains most of the same information.

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.
