Add configuration to enforce minimum size when
generating a RSA key, it's default value is 1024
bits since this the minimum secure value currently
but it can be any value greater than or equal 128
bits. Tests were modifed to accommodate for this
change.

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.

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

Mostly a search and replace with just two manual changes:
1. Now PK and TLS need MD light, so auto-enable it.
2. Remove the old function in hash_info.[ch]

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

Changes in test_suite_psa_crypto are to enforce the dependency
on ECP_C which is mandatory for some key's derivation.

Instead of using the legacy mbedtls_ecp_gen_keypair() which makes
use of ECP's math, when USE_PSA_CRYPTO is enabled then the new
function pk_genkey_ec() is used in test_suite_pk.

Instead of using the legacy mbedtls_ecp_check_pub_priv() function which
was based on ECP math, we add a new option named eckey_check_pair_psa()
which takes advantage of PSA.
Of course, this is available when MBEDTLS_USE_PSA_CRYPTO in enabled.
Tests were also fixed accordingly.

Now that Entropy doesn't need it any more, we can have driver-only
SHA-256 (and 224 with it) in the non-USE_PSA component too.
This reveals a missing PSA_INIT in a PK test using SHA-256.

Introduce MD_OR_USE_PSA_INIT/DONE. This will likely be used everywhere
in X.509 and SSL/TLS, but most places in PK only need USE_PSA_INIT/DONE.

These tests check for failures, but can only fail where SIZE_MAX
exceeds some limit (UINT_MAX or UINT32_MAX) and do not fail
in this way otherwise - so guards are needed.

As a public header, it should no longer include common.h, just use
build_info.h which is what we actually need anyway.

Cases where radix was explictly declared are removed in most cases,
replaced using script. bignum arguments are represented as hexadecimal
strings. This reduces clutter in test data and makes bit patterns
clearer.

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.

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
