ctx->buflen now returns the amount of valid data in ctx->buf.
Unencrypted buffers were already ok, but encrypted ones were
used to return the length of the encrypted buffer, not the
unencrypted one.
This commit fix this behavior for encrypted buffers.

ECJPAKE_C only needs MD_LIGHT and it allready auto-enables it in
config_adjust_legacy_crypto.h, so nothing to check here.

We're already making sure of that in
include/mbedtls/config_adjust_psa_superset_legacy.h - no need to
double-check here.

After this change, check_config.h does not have any #defined except:
- the standard header double-inclusion guard
- short-lived helpers that are #undef-ed in the same paragraph

Those were only used for KEY_EXCHANGE_ECJPAKE, but had a much larger
scope than needed. We actually don't need those macros if we distinguish
between cases when expressing dependencies for this key exchange.
The remaining helper macros are all short lived.

It always uses MD now. (The "fall back" to PSA Crypto was only in the
1st iteration of driver-only hash support, before we changed the
architecture to make everything go through MD.)

None of the TLS code is calling low-level hash functions directly. So
the correct dependencies here are MD_CAN.
(I checked and this was the only occurrence.)

Simplify: let's take advantage of the MD_CAN macros instead of doing it
again ourselves.
Fix: SHA-3 was forgotten.

Similarly to check_config.h, also build_info.h should consider
MBEDTLS_PSA_CRYPTO_CLIENT as the define which signals that PSA
Crypto APIs feature are being required in the build (possibly
due to the client/service architecture). It is automatically
enabled if CRYPTO_C is enabled, but only at config_adjust_legacy_crypto.h
which happens after the inclusion of the config_psa.h is needed

When check_config needs to evaluate the availability of a feature
through a PSA API, it should look for MBEDTLS_PSA_CRYPTO_CLIENT
instead of MBEDTLS_PSA_CRYPTO_C, to be able to cover the case
where the API is provided through a client/service interface.

The main purpose of the change is to
know from the status, at any point in
the handshake, if early data can be
sent or not and why.

The only real contraint on the raw buffer is that it is large
enough to contain 2 coordinates. Larger buffers are therefore
allowed and the extra data will simply be ignored.
Note = trying to impose a strict sizing on the raw buffer causes
several failures in test suites. This suggests that it is
quite common to use larger buffer to store raw signatures.

Allow the function to support DER buffers than what it is nominally
required by the provided coordinates. In other words let's ignore
padding zeros in the raw number.
