TLS 1.2 has never been able to work with only SHA-512, it just happened
to pass previously because the declared dependencies were too lax.
(Probably related to the fact that in the past we didn't distinguish
between SHA-512 and SHA-384 in dependencies.)
So, just disable all of TLS in SHA-512-only builds. While at it, tune
build_info.h to make this easier - it already had partial support for
disabling TLS 1.2 or TLS 1.3 in an easier way, but not both of them at
the same time.

Then manually revert programs/pkey/ecdsa.c as it's using a low-level
hash API.

As a consequence, MD_C is now enabled in component accel_hash_use_psa.
Fix guards in X.509 info function to avoid this causing a failure now.

This enables access to all available hashes, instead of the previous
situation where you had to choose by including MD_C or not.

Same note as previous commit regarding guards.
Note that we could auto-enable MD_LIGHT only when SELF_TEST is defined,
and even only when SHA1_C is defined too, but somewhere down the line
we'll want to auto-enable it for the sake of other RSA function (not in
selftest and could use any hash), so there's little point in optimizing
the temporary condition, let's use the simple one upfront.

But, for now, still guard things with MBEDTLS_MD5_C, as md.c can only
compute MD5 hashes when MBEDTLS_MD5_C is defined. We'll change the
guards once that has changed.

For multi-part operations, we want to make the decision to use PSA or
not only once, during setup(), and remember it afterwards. This supports
the introduction, in the next few commits, of a dynamic component to
that decision: has the PSA driver sub-system been initialized yet?

These new symbols will allow code to call the md module and benefit from PSA
accelerator drivers. Code must use MBEDTLS_MD_CAN_xxx instead of
MBEDTLS_xxx_C to check for support for a particular algorithm.
This commit only defines the symbols. Subsequent commits will implement
those symbols in the md module, and in users of the md module.
