The new name better reflects the fact that the 1st parameter
is just the EC family and not the curve.

Move the mbedtls_ecc helper functions from psa_core to psa_util.
These files are not implemented as part of the PSA API and should not
be part of the PSA crypto implementation.

ECC macros used in the following files:
library/pk.c
library/pk_wrap.c
library/pkparse.c
library/pkwrite.c
library/ssl_misc.h
library/ssl_tls12_client.c
FFDH macro use only in library/ssl_misc.h so could possibly be moved
there, but it seems cleaner to keep it close to the ECC macros are they
are very similar in nature.

Most functions in psa_util.h are going to end up there (except those
that can be static in one file), but I wanted to have separate commits
for file creation and moving code around, so for now the new file's
pretty empty but that will change in the next few commits.

The header clearly states all functions here are internal, so we're free
to remove them at any time.

The previous informal comment was not enough to prevent it from being
used in several places in the library. This should have more effect,
considering with have builds with DEPRECATED_REMOVED.

As usual, just a search-and-replace plus:
1. Removing things from hash_info.[ch]
2. Adding new auto-enable MD_LIGHT in build-info.h
3. Including md_psa.h where needed

All PSA crypto error codes fit comfortably in 16 bits and we have no plans
to ever change this. So use 16 bits to store them, which reduces
mbedtls_error_pair_t from 8 bytes to 4 bytes.

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).

This is mostly:
sed -i 's/mbedtls_psa_translate_md/mbedtls_hash_info_psa_from_md/' \
library/*.c tests/suites/*.function
This should be good for code size as the old inline function was used
from 10 translation units inside the library, so we have 10 copies at
least.

Depending only of our software implementation was too strict. The
function can be useful when only the PSA implementation is available,
since oftentimes the algorithm will still be expressed as an md_type for
legacy reasons.
