When early_data extension is enabled and sent in ClientHello,
the client does not know if the server will accept early data
and select the first proposed pre-shared key with a ciphersuite
that is different from the ciphersuite associated to the selected
pre-shared key. To address aforementioned case, we do associated
verification when parsing early_data ext in EncryptedExtensions.
Therefore we have to assign the ciphersuite in current handshake
to session_negotiate later than the associated verification.
This won't impact decryption of EncryptedExtensions since we
compute handshake keys by the ciphersuite in handshake not via
the one in session_negotiate.

Same test cases as in the previous commit.
Remove the redundant symmetric crypto dependency.
The dependency is ensured by the fact that:
1) the test case forces a cipher suite
2) ssl-opt.sh enforces automatically that the
forced ciphersuite is available.
3) The fact that the forced ciphersuite is
available implies that the symmetric
cipher algorithm it uses is available as
well.

Fix some dependencies on symmetric crypto that
were not correct in case of driver but not
builtin support. Revealed by "Analyze driver
test_psa_crypto_config_accel_cipher_aead vs reference
test_psa_crypto_config_reference_cipher_aead" in
analyze_outcomes.py.

While the PSA builtin implementation of cipher still depends on
CIPHER_C, the same is no more true for AEADs. When CIPHER_C is not
defined, BLOCK_CIPHER_C is used instead, thus making it possible
to support AEADs without CIPHER_C.

Some PSA_WANT symbols do not have a 1:1 matching with legacy ones.
For example, previous to this commit:
- CCM_C enabled both PSA_WANT_ALG_CCM and PSA_WANT_ALG_CCM_STAR_NO_TAG
even thought the two are not equivalent (authenticated VS
non-authenticated).
- there was no legacy equivalent for ECB_NO_PADDING
What it is common to both PSA_WANT_ALG_CCM_STAR_NO_TAG and
PSA_WANT_ALG_ECB_NO_PADDING is the fact that the builtin implementation
depends on CIPHER_C. Therefore this commits adds this guards to
select whether or not to enable the above mentioned PSA_WANT symbols.

Move all changes local to Mbed TLS into config-tfm.h (except for commenting
out a couple of #include's).
