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.

These fields need to be enabled for 1.3 even if MBEDTLS_USE_PSA_CRYPTO isn't (1.3 should always use PSA).

Initially this function was doing something because the output format of
psa_export_public() didn't match the ECPoint format that TLS wants.
Then it became a no-op then the output format of psa_export_public()
changed, but it made sense to still keep the function in case the format
changed again. Now that the PSA Crypto API has reached 1.0 status, this
is unlikely to happen, so the no-op function is no longer useful.
Removing it de-clutters the code a bit; while at it we can remove a
temporary stack buffer (that was up to 133 bytes).
It's OK to remove this function even if it was declared in a public
header, as there's a warning at the top of the file saying it's not part
of the public API.

Relying on a PSA_VENDOR macro is not ideal, since the standard doesn't
guarantee this macro exists, but OTOH relying on
MBEDTLS_ECP_DP_xxx_ENABLED was even less ideal, so I believe this is
still an improvement.

We had ECC then PK then ECC, move PK to the end, now all ECC things are

Also remove preprocessor logic for MBEDTLS_CONFIG_FILE, since
build_info.h alreadyy handles it.

Although SHA512 is currently required to enable SHA384, this
is expected to change in the future. This commit is an
intermediate step towards fully separating SHA384 and SHA512.
check_config is the only module which enforces that SHA512 is
enabled together with SHA384.

Clang 11 has stopped using the old comment system to mark deliberate
fallthrough, and now demands marking of such with
__attribute(fallthrough). Given not every compiler supports such
attributes and these are the only two deliberate fallthrough cases in
the project at the minute, take the easy route and just remove the
fallthrough.

There was some intentional duplication between
library/psa_crypto_random_impl.h and include/mbedtls/psa_util.h, with
the intent that the compiler would complain if one file was edited in
a way that's incompatible with the other file. However, the two files
were never included together, and in fact could not be included
together because some definitions can't be duplicated (type, static
variable).
Now library/psa_crypto_random_impl.h includes
include/mbedtls/psa_util.h, so the compiler will check what it can.
There is less redundancy since it isn't always possible to declare
something twice (specifically, types can't be declared).

Don't assume that the PSA encoding of elliptic curves is identical to
the TLS encoding. This is currently true but about to change.
The new implementation only works when MBEDTLS_ECP_C is defined. This
is ok because the function is only used with MBEDTLS_ECP_C defined.
Internally, use the corresponding function from psa_crypto.c instead.
Externally, this function is not used in Mbed TLS and is documented as
"may change at any time".
